Hi @kakarakanb do you know if this still work? Im trying too make a link that asks permission from google to get analytics records

I have no clue, honestly. You'd need to try and see, but I'd guess it wouldn't work

The google lib has changed with namespaces instead of _ now, otherwise all should still work the same
