Yes.

The detail is that "client" is not Google

@eduardokraus And what is incorrect about that? The GSA/ in the user agent actually indicates the Google Search App. Or isn't that correct?

It's not correct.

This is an access via iPhone of a student logged in watching classes in a restricted environment.

That might be possible, but which client is it actually using?
As mentioned the user agent indicates it is the google (search) app

I'd like to chime in here. If I should open a new issue, I can.

The Google Search App is more or less like an add-on to the iOS WebView. It inherits the same functionality as the WebView component. However, the Matomo report hides the information about the WebView version by only reporting the GSA version.

I would prefer these useragents reported as other iOS WebView useragents (I guess that's Mobile Safari?) with the relevant version information. For example "Mobile Safari 16.6". If the GSA information really is vital (I can't really see that it is) it could also be "Mobile Safari (using Google Search App) 16.6".
