Multiple application saml login in one OKTA Tile?

I’m currently developing an Application for our company community and most of the resources came from another site, and to be able to access those resources like images, videos, and files, the user needs to login to that site before accessing them in the main application that I currently develop.

is there a way to access multiple app using just (1) okta tile but multiple login sso?

It should login first using an SSO to the resources website then making the main application the last one to signed in and also the last one to be loaded.
