Okta tile login through api

I have okta IDP set up for org apps. These apps include some custom apps , some open source third party apps such as grafana , kibana.

I am embedding these third party URLs into my iframes. I can see that even if I logged into the okta home page. iframes will ask me to log in.

but once I log into these apps from other tabs, as long as session is same. Next subsequent iframes wont show me log in pages. which is understandable.

I was wondering is there any way for me automatically initiate app login for some of my apps.

Iframes are also included in an app which uses okta as idp for it verification.
