self-hosted chrome extension via workspace force install not showing for user

[BD]

Hi there, been stuck for a day and a half on why a self-hosted extension is not being force installed via workspace enterprise policy.

What I have done so far.

1. packed my build folder so it's .crx file
2. figured out id by going here my https://crx-checker.appspot.com/
3. hosted my .crx file at firebase storage
4. created a manifest.xml file that includes my id and the location of my .crx file
5. my manifest.xml header = Type text/xml, my .crx file header= Type application/x-chrome-extension
   1. https://firebasestorage.googleapis.com/v0/b/xxxx-xxxxxx-xxxxxx.appspot.com/o/build.crx?alt=media
   2.  https://firebasestorage.googleapis.com/v0/b/xxxx-xxxxxx-xxxxxx.appspot.com/o/manifest.xml?alt=media
6. then I added my manifest.xml firebase URL here: https://share.getcloudapp.com/ApuXyGwn
   

Is there anything else I am missing? chrome://policy -> ExtensionInstallForcelist is showing the extension ID and .xml file URL, but I can't seem to figure out why it's not force installing.

Thank You

Is it possible for the MV3 extension to be self-hosted. And I am having the same issue the self-hosted extension isn't installing with force install.

I'd like to believe so. Is yours showing in chrome://policy? At least for me I am seeing my extension ID there. just no extension
