My questions is some what similar to (question) but with some differences. I am using FCM Admin SDK, but still do not see an option to send the click_action attribute for Web Push notifications. I checked out admin.messaging.NotificationMessagePayload as well, but looks like this is only applicable to Android and iOS.
As per the comments in the above questions, this click_action is not available for web push using http v1 API (and I think FCM admin SDK as well)
Please help me on how to send the click_action attribute for a web push notification using FCM Admin SDK. If there are any other workarounds, that would be helpful as well.
Thanks in advance.
