RA6M3 usage with WiFi module ATWINC1500 with FSP 5.5.0 and ThreadX

Hello,

according to the "Renesas RA Partner Ecosystems Solutions" list, there is the possibility to utilize a WiFi module called ATWINC1500 by the company Reloc.

Could you please tell me how to use this module with FSP 5.5.0 and ThreadX?
The only place to find some driver software was this page: https://www.reloc.it/products/pmod-wifi-atwinc1500-and-drivers/
Unfortunately it refers to an old version of FSP (v3.5.x). I ran the installer but since then there is apparently no new WiFi stack available. Am I missing something here?

Thanks in advance.
