In the code, we created a function named register_my_custom_submenu_page and we used add_submenu_page to add the item to the navbar as a child of tools.php, which is the Tools page.
Please check the parameters part in this page to know about the arguments we passed in. Then we used add_action to run our register_my_custom_submenu_page function. Finally, we created the function my_custom_submenu_page_content to display contents in the page.
