DAC Arcam RLink Bluetooth

Hi all, I just installed Volumio on my Raspberry PI 4 that I would like to pair with the Arcam Rlink bluetooth DAC, which is connected to the amplifier, but it sems that this feature is not supported or, simply, I can't find it. I checked here, on the guise and on the internet but I could not find anything helping so far. Can I ask you community if there are chances to have this connection happening? Thanks!

It is not possible to output to BT. But search the forum, some users did it.
