Beginner Adapter for Fujica X-mount SLR Lens for Fujifilm X-A5 Mirroless Camera (X-mount)

[Vectorially]

Embarrassing newbie error... I bought a second-hand Fujica/Fujinon X-mount SLR lens under the mistaken stooopid belief it would be compatible with the X-mount specification for the current range of Fujifilm mirrorless cameras, specifically the X-A5.

The SLR lens is a 50 mm f/1.9 with a single bayonet, and was attached to a STX-1N SLR.

Can some kind and forgiving soul please signpost me to place(s) online selling the appropriate adapter to be able to use the SLR lens on my mirrorless X-A5? I can only find adapters for M42 and M39 lenses which, as far as I can understand, are not of the Fujica X-mount design.

I googled it as wasnt aware of a mount other than M42 so will now look out for that with vintage lenses
Wikkipedia says-

The Fujica X-mount was a lens mount created by Fujifilm in the late 1970s for the new Fujica SLR lineup: AX-1, AX-3, AX-5, STX-1, STX-1N, STX-2. It replaced the M42 screw mount used on their earlier SLRs.

The only readily findable adaptor seems to be from Fotodiox
