SAP Solution Manager 7.2 SPS14, Fiori Apps, IOS mobility & more

Hello,

We want to use a mobile solution for ChaRM, like validate RfCs, approvals, status changes, etc.

There are some blog posts about that, but all are very old.
In the past, there was an ITSM app.

Now we have 2022 and all these circumstances.

What are actual the state-of-the-art solutions to work mobile and independent from SAP Solution Manager?

I wasn't able to find any IOS app or any other suitable solution for that.

Has anybody a solution for this or any idea how to make the process more mobile?

Many Thanks!
