Intune - using SDK for an new application - keychains

Hello All,

got an question. If we want to use an Intune SDK in custome app. Where do we set-up the keychains? Does someone have some experience with this?

According to this document:

There have to be something like (teamID) that will share the key between two apps. Our developer thinks that this (teamID) has to be set somewhere at Intune for it to work (as it have to be shared between apps)

I was consulting this with the Microsoft and their knowledge base:

And there is zero info if there is some action on Intune side that is needed.
Anyone have some knowledge about this?
