Hello

I was hoping to get some guidance with regards to using an existing identity for customers - i would like to include a grandnode ecommerce application into our current stack however our front end and IdP already has an existing user pool in AWS cognito. I would like to reuse this identity for the customers in grandnode and was wondering if something like this has been attempted before ? Essentially what it boils down to is allowing my users a single area where they can manage their identity and password but leveraging that in grand node - a single sign on experience if you will
