Mini zigbee switch (TUYA) MS-104Z pairing issue with Sonoff ZBBridge

I am trying to pair a TUYA MS-104Z (Zigbee) mini switch with a Sonoff (Zigbee) ZBBridge, by using the Ewelink App and standard firmware on the Sonoff bridge. Both should support Zigbee 3.0. I had no luck yet to get the switch paired to the Sonoff Bridge.

Has anybody experience with this, and got it working?

Or are the 2 devices not compatible, or is the TUYA switch not recognised by the Ewelink App?
