Save the access token, refresh token and expiry along with user, in the user table or a new datatype.
You can maintain one row for each user and keep updating it using backend workflow.
OR
You can create new row each time yoh get a new token.
You can keep the new datatype as private and ignore privacy rules in the api workflow to schedule actions for relevant user.
