Hi @Presh,
You can use the Trigger Notification Action! See here : https://youtu.be/0kSDrfwGJyo?t=1161
Groups chats? You need to add users to a many to many relationship inside the chatroom collection. And then same way you can show current conversation > messages and all users inside that conversation can see that messages!
Yongki built a great app for this! : ๐ฉโ๐งโ๐ฆ Group Chat Template "70% Discount" for Template only
