Gutenberg ComboboxControl to query posts

Hi there,

I’m looking for code examples for Gutenberg ComboboxControl that allows the user to select a post of a certain post type created by a particular user by typing a partial post title.

The linked page has an example but with preset options. What I’m looking for is to perform searches for a typed post title in the background and let the user pick one from suggest items.

Would be appreciated if somebody can post a link to an example or a code example here. Thank you.
