Has anybody played with the youtube sensor - and launch video from lovelace?

Hi All

I’ve set up the youtube sensor, and I have of course drzzz as one of them, paul hibbert as one, and then a danish guy called repairguy.
It nicely shows what the latest video is, and I’ve also implemented a ‘notify’ function when a the latest video changes.
I would however very much like to just click in the lovelace card, and launch the video.
I have them shown in an entities card, so I was trying to set it up like this:


But apparently the url isn’t correct (even though the template test in developer tools gives the right value)
I would of course like to keep the layout as much as possible, but is the entities card the right choice for this? What have you done?
