Frigate Event MQTT-In node: Temporarily suspend mqtt-in flow to parse payload to next node

I have a flow that listen to frigate/event and send the final snapshot of the event to my mobile phone. It has been working great. However, The mqtt-in event happens quite frequently and so my phone is getting quite a lot actionable notifications. Pershaps sometimes is way too frequent and the jpg attachment in the actionable notification becomes 404 error.

Is there a way to pause the flow right after my phone receives the notification for let say 1 minute, and then automatically resume for next frigate event?

Thanks!

@Mikefila Thanks, unfortunately I cannot import your node-red. I ended up using simple gate node to block the mqtt traffic with a delay loop in between open/close gate.
