I’m not entirely sure the name given to these links, but the class is called “row-actions”.

You will want to use the post_row_actions
filter https://developer.wordpress.org/reference/hooks/post_row_actions-2/
For example, to add a link, you could try something like:
function add_custom_link($actions, $page_object)
{
$actions['custom_link'] = '<a href="http://www.example.com">My Custom Link</a>';
return $actions;
}
add_filter('post_row_actions', 'add_custom_link', 10, 2);
