Block sidebar element - Adding content toggle / faqs

Hi,

I would like to add a content toggle / faq in the right sidebar element.

I tried by using the content toggle element from Ultimate Blocks but it doesn't work as the styling is not picked up. I understand why after seeing your video on it.

So my question is: Do you know of a way to add a content toggle in a block element for the sidebar?

As content toggle is not among the default gutenberg block or in generateblocks -are there any other third party blocks that you know are compatible inside the block sidebar element?

Thanks for any advice.

Kind regards
Lars
