How to remove control panel and resources

Hi,

I have created a new control panel from the option:

Settings -> Lovelace control panel

I would like to delete it but I cannot find the way to do it. Is it necessary to delete the configuration of some file or something?

The same goes for resources.

I have already solved the problem, it was an edge browser problem, with another browser it is as simple as clicking on it and selecting delete.

regards
