remove help Tags

I want make wordpress “clientfriendly”. So I decided to add some helptext to every post.php page.
Now I want to remove the default help Tabs and only show my own.

I found this:
https://developer.wordpress.org/reference/classes/wp_screen/remove_help_tab/
But I’m not sure how to use it.
I foundy many tutorials how to remove the complete help text but this ist not what I want. I only want to hide the default ones like:

• customize-display
• title-post-editor
• inserting-media

… and so ones

Thank you for your help.
