It was a problem! Express LRS arming just doesn't work properly with ArduPilot. But now it does! All you need is:
* Yaapu Telemetry https://github.com/yaapu/FrskyTelemetryScript
* EdgeTX https://edgetx.org
* ExpressLRS https://www.expresslrs.org/software/switch-config/?h=sticks#switch-position-channel-resolution
* RadioMaster TX16S  https://www.radiomasterrc.com/products/tx16s-mark-ii-max-radio-controller
and a little bit of setup, all explained in this video. Check below for the channel markers.
