How can database privileges in phpMyAdmin affect the visibility of databases in the navigation menu?

Database privileges in phpMyAdmin can affect the visibility of databases in the navigation menu by restricting access to certain databases based on user privileges. To solve this issue, you can grant the necessary privileges to the user accessing phpMyAdmin so that they can see all databases in the navigation menu.
