Argon One V3/Umbrel how to get fan working?

With the release of Umbrel 1.0 on the 18/3 I’m planning on setting up a node that will run Umbrel.
With Umbrel installed on the SD card and an attached NVME SSD drive for the BTC Blockchain.

My question is, how do I go about setting up the fan and maybe the home button? As you can tell I’m new to the Umbrel/Rasberry Pi world. Have spend days trying to find info on this. The fan/power button seems to be an issue that with the Argon One case. For us newbies anyway. Any help here would be much appreciated.
