Vl550/350 not allowing to play a notification sound through vl550 when something changes (sensor, switch etc) using the speaker companion smartthings smartapp

Hi, I purchased a vl550 with the main intention of having it play a barking sound when an outdoor sensor or switch is triggered.

I’m using the speaker companion smart app in smartthings. Whilst it allows me to control the speaker if something happens, it doesn’t give you an option to play a sound.

There are 2 more options in the speaker companion app. One is ‘play a notification’ and ‘play weather report’. If you select either of these it says that no speaker is found.

My question, which speakers are compatible? I thought this samsung speaker would be but it’s not integrating.
