2 column component with slot

Hi everyone!

How can I create a component where I can insert different components? I tried using the new slot element, but I wasn’t able to get it working.

What I want: I create a 2-column empty block, and then I drag, for example, 2 buttons with different styles into it or 2 images. I built this structure in Bricks, but when I try to use it in Gutenberg, nothing indicates the 2 empty columns where I could place the buttons.

It works fine in GutenBricks as well; there it’s called an InnerBlock. In Gutenberg, it clearly shows a “+” icon to indicate where I can insert a component.

Thank you!
