How to debug HTTP $options['hooks']->dispatch

Example

$options['hooks']->dispatch('requests.after_request', [&$return, $req_headers, $req_data, $options]);

it translates so

do_action_ref_array( "requests-requests.after_request"

So in this case you can do:

add_action( 'requests-requests.after_request', 'ramon_debug', 10, 4 );
