Not sure why this Google authorize button is being created, because I'm connecting to a different service. Maybe related to this? https://github.com/dnplus/streamlit-oauth/blob/55baab68c21e8d02d28846eddf6798568aab4e11/streamlit_oauth/__init__.py#L153 I don't believe I've personally set _RELEASE anywhere.

Thanks for the library!
