poe speakers support

[Buster14]

Hi would something like this work with this plugin?

Manual says it supports multicast on page 13

If it does, is there any instructions? Not too familiar with multicast-ing. Just need it to play a music playlist non stop actually, so if this plugin could somehow make poe speakers detected as speaker by HA, then the rest shouldn't be too hard.
