Installing and using harmony-card?

So im unable to get this working. Ive installed and also added the resource to the dashboard with the URL to the js file but still wont show up as a lovelace card in the dashboard. Can anyone help me out?

Thanks

As the card has not been updated in 8 months, it’s likely plainly broken on a 2022.6.
You might open a ticket on github, but my assumption would be that it’s abandoned
