I am having trouble pouring firebase authentication information into Bigquery.

I would like to pour the authentication credentials of the firebase that I use to handle the credentials for analysis into BigQuery, but it is not working.

https://support.google.com/firebase/answer/6318765?authuser=0
I tried linking BigQuery and firebase as described in , but authentication doesn't seem to be compatible, so I can't get any data.
What should I do?I'm sorry to ask you a question from a beginner, but I appreciate your cooperation.
