RingCentral App - Direct SSO Link

Currently - our users follow the below workflow for signing into RingCentral Glip:

1 - User signs into IDP

2 - User navigates to: https://app.ringcentral.com

3 - User selects "Sign in"

4 - User selects "Single Sign-on"

5 - User enters company email

6 - RingCentral grabs user identity from IDP & signs them into app

Ideally, I would like to skip steps 3-5 (i.e. pass the user's email as a parameter in a login request, or hit a custom tenant url which performs an automatic metadata lookup)

You already do this for other services, for example:

https://service.ringcentral.com &
https://login.ringcentral.com/api/sso/startup?email=
