I have the following code in a custom submit handler:
$status = Drupal::messenger()->messagesByType('status'); foreach ($status as $delta) {    // Here I want to extract the text string that is in $delta. } The variable $delta now contains this:
delta => stdClass Object (     [__CLASS__] => DrupalCoreRenderMarkup     [string:protected] => Article request My article has been created. ) How do I get the protected string from $delta?
I’ve already tried some methods, but so far I haven’t found one that works.
Here are those tried so far:
Error: Call to undefined method DrupalCoreRenderMarkup::getMessages()
Error: Call to undefined method DrupalCoreRenderMarkup::toString()
