How can I reduce the number of Facebook Messenger notification sounds on Android?

I have recently switched from an iOS device to a Samsung S20+. On my old iPhone, when I received 10 consecutive messages on Facebook Messenger I would only hear the sound of the first and second notification. On Android I hear all 10 sounds, and it is extremely annoying. Does anyone know how can I reduce the number of notification sounds on Android, so they work the same way as they did on my old iPhone?

Thank you.
