Repeat Sonos "Play soundboard sound"?

I send a sound (police siren) from soundbord to Sonos using the Sonos command “Play soundboard sound” - works perfectly.

But how can I loop/repeat it - until I stop it? I tried setting the Sonos → Repeat to Repeat track, but it still just play it once.

How can I loop (repeat) a sound I send to Sonos?

You can start a new flow, with a delay equal to the length of the soundfile. Make that flow start itself again after 50s; this loops forever, until
1- you turn the switch off (in the example a v switch called “Youkebox”)
2- Homey restarts / restarted

Flow 1

Flow 2
