Hi @sujeetnishad,


I'm afraid you cannot deeplink the chat to a guest user.  

Referring to documentation supported user ID is AAD UserPrincipalName, but guest AAD UPN is not working.


Is your requirement to open a chat exactly to a guest user in your tenant?

Yes, you are right!
Yes, we need to open the guest user chat on click for which we are using the deep link!
