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?

Cheers
