Spotify Device Selection Item

Dear Community

I use the Spotify Bridge binding.
Now, I want to add all active devices in a dropdown menu.

The string item “devices” contains all active devices from Spotify.
When I use the default selection widget, I can see all devices.
But it’s not at all clear to me how the selection widget reads these devices out of the string.

When I look at the string in visual studio it looks like this:

How can i read out the devices from this string and write them in a dropdown menu?

Thanks in advance!
