Pushover - play a custom notification sound

Hi.
https://pushover.net/sounds/build

I have uploaded custom notification sound.
I don't see them in the pushover node – sound.
Is there a way to fix this?
Thank you.

The read mei suggests you can pass the sound in the message: node-red-node-pushover (node) - Node-RED

Also confirm exactly which pushover node package you are using (there is more than one contrib node in the library - you may be using the old version)

Yes. I have node-red-node-pushover 0.2.2


I dont know if the node is even supposed to list your added sound. Have you restarted node-red? refreshed the borwser? Have you tried setting msg.sound in the msg that triggers the pushover node?
