Which thru axle adapter for MTB 12x187 Boost rear axle?

I've just bought a Tacx Vortex second-hand. I would like to use my Orbea Rise mountain bike with it. Orbea say that the rear thru axle is Boost 12x148 hub spacing, with the thru axle being 12 mm diameter x 187 mm length x 1.5 mm thread pitch x 15 mm thread. Does anyone know if this will work on the Vortex, and if so which adapter I need to mount it? I have read Garmin articles on setting up the vortex and which thru-axle will fit my bike but can't seem to figure it out. Thanks!
