Create a config action to place a block in a dashboard

It would be so nice to have.
Thanks, Martin, for starting this issue!

I'm with this idea for a Config Action to place an inline block in the selected section's region.
Maybe add a new section at the start or the end of the dashboard with pre-selected blocks
A bit like what the Section Library → is doing.

Thinking of

addDashboardSection:
  order: last
   ...

addDashboardBlock
  region: first
  ...

Exmaple:
We had a case which needed the following blocks in the Drupal CMS starter recipe.
Which could be in a new optional recipe. or add them directly to the Welcome Dashboard

Publishing content
Shows a list of publishing-managed content on the site.

My drafts Block
Shows a list of all draft content for the currently logged-in user.

Scheduled Block
Shows a list of all content scheduled for future publication on the site.

The Dashboard entity type is a config entity, not a data entity type.

What do you think? Should this config action be in Drupal Core with the Layout Builder?
We managed that with Content data entities ✨ Add a Normalizer and Denormalizer to support Layout Builder RTBC
What could be the best method to manage this with config entities?

Dupe of ✨ Provide a Config Action so recipes can add a block to a dashboard Active which is postponed on core issue. Probably nothing will need to happen on dashboard itself.
