Issue with add_meta_box function on Divi theme

I have the basic function added to my child them to make this show up in my edit page but need a little help finalizing it.
Here is a 2 min video I made for you

Here's the code being used:

add_action( 'add_meta_boxes', 'ampforwp_title_custom_meta_for_divi_category_builder' );
function ampforwp_title_custom_meta_for_divi_category_builder(){
add_meta_box( 'ampforwp_title_meta', __( 'Show AMP for Current Page?' ,'accelerated-mobile-pages'), 'ampforwp_title_callback','et_extra_options','side' );

    Hello Greg,

    We would need to test code with Divi and AMP plugin. At the moment I don't have access to both of those (they are paid products), so could you maybe zip those and send us for testing purposes?

    Could you please send in the following via our secure contact form :

    - Mark to my attention, the subject line should contain only: ATTN: Kasia Swiderska
    - Do not include anything else in the subject line, doing so may delay our response due to how email filtering works.
    - Link back to this thread
    - Link to zipped theme and plugin on service like dropbox
    - Include any relevant URLs for your site

    IMPORTANT: Please make sure you select "I have a different question" for your topic, so it doesn't go back to the forums - this and the subject line ensure that it gets assigned to me.

    Please confirm here that you send those credentials

    kind regards,

Thank NAME, for their help.
