Any Devi/ Bhairavi upasakas

I've been following Rajarshi Nandys videos and he mentioned about volenteer activities going on through Kamakhya Bharava Upasaka foundation in Hyderabad and in order cities, but i didn't find a way on how to connect with them. Anyone from this sub aware of this or any other foundations that worship Devi and get involved in volunteer activities. I want to be part of that Sangha. P.S: For anyone who done know, Rajarshi Nandy is a spiritual person who has an YouTube channel and guides order sadhakas/ upasakas Khamakya temple is a shatipeet in Gauhati
