Legacy analytics doesn't work for previous project

I updated a new version of my game pulled from Github and use my previous project ID to link the analytics service but the console showed this:

We would recommend that you take this opportunity to upgrade to UGS Analytics by installing the Analytics package via Package Manager. Otherwise we may be able to associate the projectID in our database, please open a support ticket here

But UGS Analytics doesn’t support WebGL. How could we collect data from other users?

Point taken, we may be able to associate your legacy ProjectID as mentioned
