SAML IdP-initiated from Okta Apps Portal

Hi,

We configured SAML enterprise connections for our customers to be able to login to our application via Okta.

Everything works fine, but we now want to let our customers to login via the Okta Apps Portal (IdP-initiated login flow).

From my research and attempts, I’ve come to an understanding that this is not very simple like doing so with OpenID connections.

Do I have to implement a new page that takes the connection query parameter and redirects to Auth0? and where do I put that new page URL?

I’d appreciate any help here.
Thanks!

I tried configuring IdP-initiated with SAML in the Auth0 enterprise connection, with the query string as redirect_uri=xyz.com and it doesn’t work
