Google FCM messaging parameters

[Rene61]

Hello,

I'm using Google Cloud Messaging on serveral devices. Some are in use and others are offline beining charged.
When I turn on one of het devices after charging the "old" messages are received and acted on.
For instance a door bell event.
I would like to put a maximum lifetime on these messages. FCM has parameters for this: https://firebase.google.com/docs/cloud- ... server-ref

Would it be possible to create user definable parameters for Google Messaging in Domoticz?

Thanks in advance.
