Can't connect signals to portrait script

[M4Z3-R]

I have been trying to figure out how to swap the animations on my character portrait. I understand the idea of connecting Dialogic's signals to the script used for the portrait, and have found earlier answers on what signals to use.

Yet when trying out something like Dialogic.Text.about_to_show_text.connect(_about_to_show_text) in the _ready function of the portrait script i don't actually receive any signal when i would expect one, the script i'm trying to connect is the sample scene script which extends DialogicPortrait.

I also can't seem to figure out how to connect to finished_revealing_text, i tried things like: DialogicNode_DialogText.finished_revealing_text.connect(_text_finished) but nothing i could come up with ran without errors.

Am i supposed to connect the signals in the DialogicPortrait script at all? If so, how would i write that exactly in the _ready function?
