I've got a custom theme that I'm using on multiple sites, the issue is I'm trying to incorporate Layout Builder and when I add a custom block that has a twig file it will not allow me to edit or delete the block. I found that some out of the box themes have patches but there is nothing that I can find for getting this to work if you have a custom theme. Can anyone point me in the right direction to get this to work with my custom theme?
is it possible to create a custom block (with content) at theme installation with a "/config/optionnal/configuration-file.yml"?
i know already how to place a native system block with "/config/optionnal/configuration-file.yml" but i am wondering if it's possible to create a custom block with content whit it.
I saw in a theme that it's posibble to create a new type of block whit "/config/optionnal/configuration-file.yml", so it might be possible to create a basic custom with content i suppose.
