Need help in creating an Internet Hotspot on Mac OS Big Sur 11.3.1 for other devices

My system details

HP OMEN 15 Laptop

i7-10750H, 8GB RAM, Kioxia SSD, Intel wifi 6 ax201, Rtl8111 LAN

So, Everything runs fine on my system and the only need is now to enable the wifi hotspot on my hac. I use AirportItlwm.

This is when I try enabling hotspot. No option to select in channel.

There is no option to select in Channel.

I would really appreciate if someone can tell me what to do or the reason why it could not be done.
