Connect Instinct 2 to SRAM AXS shifter?

I want to track my shifts on MTB activities. I don't need to view the data field on the watch, but I want to see the data in AXS Web afterwards.

I've tried to sync use the "Search All" function, but it's not coming up. It seems that the shifter sensors are only available on cycling computers? Speed/cadence sensors can be paired with the Instinct 2 so this seems like a weird omission.
