Trying to create web push notification with firebase and need to add two gcm_sender_id in manifest.json(same file) but it accepts only one id and in string only. Need to add these two gcm_sender_id. So that I can migrate all my subscribers from another platform to FCM.
{
"gcm_sender_id": "9***********",
"gcm_sender_id": "103953800507"
}
If I use gcm_sender_id of FCM then I am unable to send web push notification from the old platform. On the other hand If I use the sender ID of old platform instead of FCM then my Token is not getting generated. Else everything is working fine. Unable to find anything. Is there any solution?
