Playlist with GPIO button - button plugin

Hello,
I have a problem in the new volumio version.
Well, I can not cope with the use of the “buttons” plugin to run the selected playlist with the command: volumio.local / api / v1 / commands /? Cmd = playplaylist & name = Rock
On the next version, I managed to replace the next “next” on the playplaylist and it worked.
Does anyone know how to easily hang a playlist from a pram using a plugin?

Thank you.

Nobody has an idea? :frowning:
