Domain menus enabled does'nt get displayed on frontend inspite after configured at the backend domain wise

A details documentation to follow the steps from start till it is displayed on frontend.
Our menu created, enabled & activated on main navigation region while the default menu set is disabled but on frontend it shows empty.

I'm not able to reproduce your issue given the amount of information you have provided.

But note that the domain menus are blocks and so you need to configure your blocks to see domain menus.

The block is been configured , enabled & the default main navigation is been disabled.
The block is'nt visible anywhere nor it can be fetched in any of the hooks on front end inspite of placing the block.
The backend setting is done properly but on frontend not visible anywhere nor can be fetched in either ways.
Hope this helps you to suggest a solution.

I have verified on a clean standard profile d10 install with olivero theme that domain menus blocks do display.

The domain menu must have menu items for the block to display.
