How to open a PM through a Notif click in BAE 2.0

In my code, I would like a PM to appear when the notif is clicked.

The true parameter at the end is to make it so it cannot be replied to, and I have tried doing it without the ending but it doesn’t work regardless.

As you can see in this photo:

I used the true parameter to make it so it cannot be replied to. If I don’t use the notif feature, it just pops up.
