Hi Srinu, It has been long time, happy to see you (in comments at least)😀 For JSS, it might take a while before I come to it, as there are other things to complete.
Manoj, do you mean Sitecore community slack, then please fill the form, one of the Admin will let you in. sitecore.chat/ If you are asking about WhatsApp groups in India, a little bit tricky, as cannot share the invite links with the public forum. If you are on Linked In, can you please DM, then I will be able to share the links.
