Configure Auth to avoid users entering username twice

Hi,

When users log in to my Foundry instance, they are prompted to enter their e-mail address. That will then redirect them to one of two configured IdP’s, based on their email address - and in the vast majority of cases that will be Entra.
Once there, they are prompted to enter their e-mail address again.

Is it possible to configure things such that we either:

  1. pass the email entered on the Foundry login form to Entra so it’s prefilled?, or
  2. have the Foundry login form not request an email field, but instead show a dropdown to select the IdP, and a button that takes the user there for them to enter their e-mail address?
