Hello @knguyen2011,
Thank you for contacting the support.
You can use the rank_math/indexing_api/capability
filter hook to change the required capability from “manage_options” to a different capability.
For example, this is how you can restrict the admin page to the users who are allowed to write posts:
add_filter( 'rank_math/indexing_api/capability', function() { return 'edit_posts'; } );
If you don’t know how to add the filter code to your site, we have a Knowledge Base page for that:

Hope that helps.
