Integrate my WeWeb app into another platform GraphQL

There is a popular software platform that many of the businesses that are my target customers use for things like CRM, resource planning, quoting, invoicing, etc. The platform offers integration with other approved apps thru GraphQL api.

Does anyone have experience getting your WeWeb app setup to connect to other platforms your users have accounts on that could share some advice? At high level I’m looking to better understand how this setup works?

Do I need to store my user’s access tokens to the platform? Do you normally pull and store data off the platform and then setup a sync strategy or always query as needed?

FWIW I’m using Xano.
