how to disable the inline CSS?

This plugins adds inline css on every page (with ids “co-authors-plus-coauthors-style-inline-css”, “co-authors-plus-avatar-style-inline-css”, and “co-authors-plus-image-style-inline-css”).

I have tried disabling it by adding the following code to functions.php in our theme:

add_action( 'wp_enqueue_scripts', function() {
    wp_dequeue_style( 'guest-authors-css' );
    wp_dequeue_style( 'coauthors-sidebar-css' );
    wp_dequeue_style( 'cap-jquery-select2-css' );
    wp_dequeue_style( 'co-authors-plus-css' );
}, 100 );

It’s still being added.

How do I remove this CSS?
