[4.x]: Change propagation method programmatically

[yannkost]

What happened?

Description

We would like to change the propagation method only for 1 user group (save all entries to all sites, only for this particular group). But I can't seem to write the necessary code with the EVENT_BEFORE_SAVE event.

I have following code in the event hook:

Event::on(
     Entry::class,
     Element::EVENT_BEFORE_SAVE,
     function (ModelEvent $e) {
         if (ElementHelper::isDraftOrRevision($e->sender)) {
             return;
         }

         $entry = $e->sender;
         if ($entry->getSection()->handle === 'applications') {
             $currentUser = Craft::$app->getUser()->getIdentity();
             if ($currentUser) {
                 $isInGroup = $currentUser->isInGroup('pm');
                 if ($isInGroup) {
                     if ($entry instanceof Entry) {
                         $supportedSites = $entry->getSupportedSites();
                         $siteStatuses = ElementHelper::siteStatusesForElement($entry);
                         foreach (Craft::$app->getSites()->allSites as $site) {
                             $siteStatuses[$site->id] = true;
                         }
                         $entry->setEnabledForSite($siteStatuses);
                         $entry->propagateAll = true;
                         $entry->setScenario(Element::SCENARIO_LIVE);
                     }
                 }
             }
         }
     }
 );

Is there any way to do this programmatically? Any help greatly appreciated :)

Steps to reproduce

1. Save an entry where the propagation method is to only save the entry to the site the element has been created on.

Expected behavior

Having the hook code working to change the propagation method only for this particular group.

Actual behavior

The entry gets saved without propagation.
