QUESTION: Custom Asset Manager. How to set bg image

Seconded, just started with GrapeJS and got it operational on my system, looking to set the background image on a header div without having to write css code :/

Actually, the knowledge of what to do on asset selection should not be part of the command itself as the action should be decided by who runs the command, eg.

editor.runCommand('open-assets', {
    onSelect(asset) {
      const cmp = editor.getSelected();
      cmp && cmp.addStyle({ 'background-image': `url("${asset.get('src')}")` })
    }
});

I'd suggest inspecting the current implementation of the command, but I have to say that is quite old, so If you'll find anything that might be improved, I'll be happy to hear that.

This is not the right solution to our question.

What I'm looking to do is add this to a component, how would we do this?
