I am handling authentication with firebase but I also need to use MSAL to handle Microsoft Graph Access Tokens. I can not figure out how to do this.

I tried following this but the answers were out of date. This answer suggested calling acquireTokenSilent() after firebase authenticates but this doesn't work with the current version of MSAL.

The newest version (v. 2+) of MSAL requires an account object to call acquireTokenSilent(), but I can't figure out how to get/make an account object. Any idea how I can make MSAL and Firebase Auth work together?
