The tool what I build require a GA4 access from users. Therefore I have to setup Google Oauth to get acess for analytic. At GCP side I setup eveythin, where I'm strugling is the xano setup.
I my understanding I have to create a new api endpoint as "get_ga4_data". Within this I can create the api request. I alrady enabled Google Oauth and I can see the pre-defined functions bu after 2 days of debugging I do not really understand the logic and do not re-create it.
Could you please describe me the process that how to create this api endpoint and how to store tokens and expires date in user table?
