Play sound on unifi smart speaker with dashbord button, new to home assistant competly lost as how to do it

new to home assistant wanted to play a sound on the new unifi smart speaker throw a button in home assistant dashboard, the speaker has a webhook that i can trigger to play a sound. have been googling how to use a bottom to trigger the webhook but not found anything completely lost now, as how to do it.

Sound like you need to use a command line command to invoke a CURL (which can send a webhook)

Probably, a rest command will do:

Use the resulting service as an action in automations or UI buttons

thanks for that, will try to get that to work with the speaker
