We've already got an app on the G Suite Marketplace, but we are now looking to publish an app so that it's available to the general public when they go to G Suite --> Apps --> SAML Apps, then it's listed.
Specifically, we're looking to have our app be listed as part of this list:
Our application is SAML-enabled, supports SCIM provisioning, and is available with other IdPs. I checked the marketplace documentation and there's no mention of SAML.
Please let me know what steps we need to take to begin the submission process. Thank you!
Requests for an app to be added to G Suite's pre-integrated SAML app catalog can be submitted using the SAML Catalog Inclusion Request Form.
Reference: Set up your own custom SAML application.
