Same mouse here (MCHOSE A7 Ultra, macOS, Chrome). It doesn't appear in the picker. Extra diagnostics in case they help:

USB: 5253:1020, bcdDevice 0x1418, manufacturer string "RealTek", product "MCHOSE A7 Ultra", 480 Mb/s

HID collections on that device:

Usage page	Usage	Report IDs	Notes
0x0001	0x02 (Mouse)	0x01	16-bit X/Y
0x0001	0x06 (Keyboard) + 0x000C Consumer	0x07, 0x0C
0xFF0B	0x0104	0x2A–0x2D	vendor, 60-byte reports
0xFF01	0x0001	0x11–0x14	vendor, 0x12 is 64 bytes in/out/feature, others 20 bytes

The 0xFF01/0x0001 collection matches the usage page/usage of your existing MCHOSE filter, but the vendor ID is 0x5253 rather than 0x3837, so the picker filters it out.
