very start of Angular 2 sublime syntax file

contexts:
  main:
    - match: ""
      push: scope:source.js
      with_prototype:
      - match: '`'
        push:
          - meta_content_scope: text.html.basic.embedded.js
          - include: 'scope:text.html.basic'
          - match: '`'
            pop: true

Does this still work in Sublime Text 4? I'm trying all the above but so far no luck. It is driving me nuts that the myVar value doesn't highlight correctly when editing an HTML file.

<h1>My Page</h1>
<script>
let myVar = `testing literal backtick here
multiple lines of string here
even more lines of string here.`
</script>

I'm honestly not sure, I've not used Angular for quite some time now and moved to VS Code as my main editor.
