Inject local HTML file into webpage via Chrome Extension using iframe?

I have a HTML file that I want to inject next to each result of a Google search result page from a Chrome extension.
I was wondering if I could use an iframe to load the HTML file?
This is instead of my current implementation that uses insertAdjacentHTML() in my Content Script and a horrible long string of HTML and inline CSS. Would much prefer to have a separate HTML file with its own CSS that I can just insert instead.
I tried:
chosenElements[i].insertAdjacentHTML('afterbegin', `<iframe src="/inject.html"></iframe>`);
but just get an iframe with a 404 page because it is looking in the 'https://www.google.com/index.html' directory rather than where the file sits.
The inject.html file is in the same place as the index.html file in my build folder for the extension. How do I access it? Can I access it?
Have you tried with
src="inject.html"
instead of
src="/inject.html"

Load JavaScript file source code as plain text and access its content using JavaScript

Is it possible to download a script file using the script tag like this
<script src="http://webserver.com/script.js"></script>
and then be able to read the loaded file content with JavaScript, like this for example:
var scriptContent = window.scripts[0].content;
What i came to notice is that the loaded JavaScript file contents is not accessible by other JavaScript files or am i wrong ?
No, it is not possible to do that.
The source code of a script loaded via src is not exposed via any API made available to JavaScript running in the page.
You could read the value of src and then fetch it using XMLHttpRequest.
The source code of specific functions may be available by calling toString() on them.

Will an .html file recognize .NET scriptlets or does it have to be convert to an aspx

I believe that I'm trying something that is not possible, but wanted to make sure. I'm trying to set a JavaScript variable inside of an html page. The index.html page to be specific.
I'm doing this:
<script type="text/javascript"> var theLimit = '<%=ConfigurationManager.AppSettings["TheLimit"]%>'</script>
Will it be recognized in an html file, or does it need to be converted to an aspx file?
HTML will not process the server-side command "<%", so you will have to change the page to a format that will process it, such as .aspx (not .ashx).

how do i access server data in separate js file

aspx file
string firsrName="jafer";
myscript.js
GetMyName();
function GetMyName() {
alert('<%=firstName%>');
}
I am not getting my value
The line alert('<%=firstName%>'); use the Web Form Page syntax. It is actually not possible to get the value like this because this syntax cannot be used in external JS files.
The simpliest (but not cleanest) method is to write the JS method into the layout file or another aspx file.

You could make a global variable in your aspx page and access it in your js using window.objectName

getting the content of script file using a local javascript

similiar How can I get the content of the file specified as the 'src' of a <script> tag? and Getting content of a script file using Javascript , I want to use script tag to load xml files for the use of a javascript code - only I need it to run locally.
so how can I access the content of the files loaded using script tag?
You can not achieve this one locally.
Loading the script will execute it and won't give you access to the src
so then the only option you would have is to load the file as an ajax call. But ajax calls don't work locally (due to security) .
