Load Plugin Form into Component Form

Question

I'm trying to load a plugin's form into my component form in Joomla4. So my components getForm method is:

$form = $this->loadForm(
    'com_mycomponent.member',
    'memberform',
    array( 'control'   => 'jform', 'load_data' => $loadData )
);

Now I wish to get any possible custom user profile plugin based on a suffix added to the profile name. So if there is a custom profile plugin with the suffix "abc" then I want to get the form located at:

JPATH_SITE.'plugins/user/profileabc/forms'

I've tried the following with no success:

$this->loadForm('plg_user_profileabc','profileabc');

$this->loadForm('plg_user_profileabc','profileabc');

Form::loadFile(JPATH_SITE.'plugins/user/profileabc/forms/profileabc');

And I guess the second part of the process is to actually "merge" the forms into one? Any advice/guidance gratefully appreciated.

If I got it right, you need first check if that plugin exists. If he does, then add the plugin form folder to the global list of form paths and then load the .xml form file.

use Joomla\CMS\Plugin\PluginHelper;
use Joomla\CMS\Form\FormHelper;

/** 
 * Check if the plugin you looking for exists, then add the form he hold
 *
 * string  $type The plugin type, relates to the subdirectory in the plugins directory.
 * string  $plugin  The plugin name.
 *
if(PluginHelper::isEnabled($type, $plugin)) {

   // Add the form path to the list of form include paths
   FormHelper::addFormPath(JPATH_PLUGINS . '/user/profileabc/forms');

   // Load the file
   $form->loadFile('profileabc');

   // rest of the code.....
   
}
