Deprecation notice contextual_help since wp5.4

[SimonvanWijhe]

Hi Cristi Burcă,

I am using the posts-2-posts plugin. Thanks a lot for the great work! Since wp5.4 the following deprecation notice is displayed in the admin dashboard. Could this be fixed?

contextual_help is deprecated since version 3.3.0! Use get_current_screen()->add_help_tab(), get_current_screen()->remove_help_tab() instead.

wp-scb-framework/AdminPage.php

Line 138 in d35d512

add_filter( 'contextual_help', array( $this, '_contextual_help' ), 10, 2 );
