Gutenberg InnerBlocks allowed types and reusable blocks

Question

I have the parent block example/parent that contains

<InnerBlocks
  allowedBlocks={['example/children']}
  template={template}
/>

And the child block example/children with

registerBlockType('example/children', {
  apiVersion: 2,
  ...

  parent: ['example/parent'],

All works as expected, but if I create reusable block from a children, it can not be inserted in any other parent again, the [+] icon will automatically create new block without the option to choose a reusable block. Is there a way to enable allowedBlocks example/children or reusable block of type example/children ?

Edit (more details)

I have the case of parent - children blocks, and inside the parent block InnerBlocks should be allowed both the children block and reusable blocks (preferable created from the example/children)

Answer 1

Yes, "why you can't insert a reusable block inside your custom block when you've used alllowedBlocks?" This is what I am trying to get

This is because you haven't allowed them:

allowedBlocks={['example/children']}

The list of allowed blocks does not include reusable blocks ( core/block ), so they are not allowed and cannot be inserted. Add core/block to the list to fix that.

Remember, a reusable block is a block of type core/block, its content belongs to another post entirely. If you say only example/children blocks are allowed, this does not mean a reusable block that contains example/children can be inserted, because a reusable block is of type core/block and has no inner blocks. You only see inner blocks in the editor because the UI is being helpful and showing you the blocks from the other post.
