Using dvswitch mobile app

I am trying to setup DV Switch Mobile on my Samsung Galaxy S23 Ultra. I don’t understand the exact procedure needed to accomplish this. Is there a document that explains from start to finish how I can set this up and not use my own physical node. I mainly want to access our local repeater Allstar node 42605 for times I am out of range of the actual repeater.

Can anyone please help?

There is also another local Ham that is trying to do this also.

Thanks and 73s
