ProcessPageEdit Redirect after Save

[Jo J]

I've created a process module that saves pages under the Home > Admin > MyPages level in the admin.

The module has a list of those pages created with links to allow further editing via PW's normal Page Edit. Upon clicking it, the form opens for editing. To stay away from the Admin territory (hidden by default), I'd like to redirect back to the module's home after saving my edits but am not successful so far.

I've been trying a bunch of ways I see here in the forum & the docs. Among some that do not appear to trigger (from my ProcessMyApp.module.php) are:

1) Derived from my understanding of API doc

init() {
   parent::init();
   	//$this->wire()->processPageEdit->setRedirectPath('/myapp/');
	$this->wire()->processPageEdit->setRedirectUrl($this->config->urls->admin . '/myapp/');
   	
}

2) Derived from Ryan's /site/modules/RedirectPageEdit.module here

init() {
	parent::init();
   $this->wire()->session->addHookBefore('redirect', $this, 'redirectAfterSave');
   
}

3) Also derived from my understanding of API doc

init() {
 	parent::init();
	$this->wire()->addHookAfter('ProcessPageEdit::processSaveRedirect' , $this, 'redirectAfterSave');
}

The redirectAfterSave:

public function redirectAfterSave(HookEvent $event) {
        $process = $event->object;
        $page = $process->getPage();

        bd($event,'Tracy no see');
        if($page->template->name === self::module_template) {
            
            $event->arguments = array($this->config->urls->admin . 'myapp/');
        }
}

What could I be overlooking?

Tried in Processwire 3.0.243 & 3.0.244

Tried with both the parent::init(); before & after

I moved the pages out of under the Admin level & to the normal Pages level. and this worked:
 

public function init() {
	parent::init();
	$this->addHookAfter('Pages::saved', $this, 'redirectAfterSave');
}

public function redirectAfterSave(HookEvent $event) {
  $page = $event->arguments[0];

  if($page->template->name === self::module_template) {
  	$app_url = $this->config->urls->admin . 'myapp/';
  	$this->wire('session')->redirect($app_url);
  }
}

I need to do more reading on the Admin mechanics.
