Can I manage/change the default flash message text? I am looking to customise the default flash message text for certain behaviours but cannot seem to find any reference to them in the code or control panel - does this exist anywhere? And could it be made editable in the CP?

I know I could do something like this but it feels hacky:

{% if craft.app.session.getFlash('notice') == 'User registered.' %}
  {% do craft.app.session.setFlash('notice', 'User registered - please check your email to activate your account.') %}
{% endif %}


Thanks.
You could for example just edit the translation file with the specific user registered flash message.

You can read more about the static translation in the docs.
