Custom element doesn't exist: restriction-card - again a stupid question

Hi,

this is my first time to install a custom card. I used HACS,
The repository shown under settings->repositories is
/hacsfiles/restriction-card/restriction-card.js?hacstag=215633404126

The card does not show up as an icon between all the other cards in the lovelace add card menu. Thats why I added it as manual - edit code in the card field.
I am using some simple example like

type: custom:restriction-card
card:
  type: thermostat
  entity: climate.house

I keeps showing “Custom element doesn’t exist: restriction-card” in the card. I know many people had similar issues. I deleted the browser cache, but I seem to do something wrong.

Any hints?

You said it’s the first time you have installed a card via hacs. If the www folder did not previously exist, then you need to restart Home Assistant before it will recognise that the folder now exists, you won’t have to restart Home Assistant to add other front-end stuff though, a browser cache refresh is enough.

Thanks a lot, restarting HA plus browser cache delete helped!
