Is it possible to prefill login email for customers if they are being sent from another app?

Problem: Because I am currently using Memberstack to manage user accounts but using Glide for some specific features, the customer has to log in twice, which makes for a clunky user experience.

Preferred solution: SSO with Memberstack

Is it possible to pre-fill a login email address or even better directly send them to the screen where they enter the code they receive via email?

I think this “Open App” button when you send an invite to join the app is the only way to pre-fill the email, but users will still have to request the PIN.
