Push Notification in CHAT

Hi to all Kodular programmers.
My question :
Is it possible to have push messages in a Chat every time messages are sent?
I used to use Onesignal and everything worked fine, now what can I use?
FCM appears, according to the developer, that it is not designed for chat.
Do you have any advice?

Use this extension

No friend, the extension manufacturer said FCM is not made for receiving notifications in Chat

this is the manufacturer’s response:
My Fcm doesn’t support chat notifications, onesignal does but due to its current situation it will be only possible in devices <android 12

So use personal message extension

what is this extension? I don’t know her, can you give me some more info?

Update onesignal fix extension its working on android 13
