No margin bottom for buttons in content with the WP editor

Description

A user mentioned on the forum that Neve doesn't add any margin to the buttons in the page content and that Gutenberg blocks should have a margin. I need help here as I don't know if it's a guideline in this regard or not.

What I did is to use the button block from WP and the buttons group block from Otter, and none of the allows the user to set a margin for the buttons. Compared to Neve, the Twenty Twenty-One theme seems to add margin to all the blockw within the page content with the * CSS selector.

Neve

Twenty Twenty-One

Step-by-step reproduction instructions

1. Add a button from WordPress
2. Add some content above and below it, like text
3. Try adding some margin around the buttons - there is no such option; I didn't find it in the Otter Buttons Group block either.

Environment info

Not relevant for this case

Is the issue you are reporting a regression

No

Reproduce the issue in WordPress using a Button block and an Otter Buttons Group block, then compare the resulting spacing with Twenty Twenty-One. Identify the theme styles responsible for content-block spacing; done means buttons have appropriate margin when surrounded by other content without requiring a separate margin control.
