Provision trust configuration as available for user logon

Hello,

we are using the Trust Configuration API to automatically provision trust configurations as part of our onboarding process for new tenants. But we cannot find a way to mark a trust configuration as "available for user logon" using the APIs. We can enable shadow users, set it as active etc. but not make it available for user logon.

Is there a way to programmatically provision a trust configuration with the flag enabled?

Thank you and best regards,
Marcus
