Question Implementing In-App Review Plugin - Android

I am attempting to complete my first game in Godot, but I’m a little hung up on if I have implemented the In-App Review plugin correctly. The plugin can be found here:

I manually installed the plugin.
I’ve followed the instructions and added an InAppReview Node to my scene.
I’ve added the InAppReview node to my scene tree and this this code to the top:

@onready var inapp_review:InappReview = $InappReview as InappReview

Next, in my _ready() I connected the signals:

inapp_review.connect("review_info_generated", _on_review_info_generated)
inapp_review.connect("review_info_generation_failed", _on_review_info_generated_failure)
inapp_review.connect("review_flow_launched", _on_review_info_launched)
inapp_review.connect("review_flow_launch_failed", _on_review_flow_failure)

Next, I added the functions for the signals, like so:

func _on_review_info_generated():
	%TestLabel3.text = "signal for generation"
	
func _on_review_info_generated_failure():
	%TestLabel3.text = "signal for generation - FAIL!"
	
func _on_review_info_launched():
	%TestLabel4.text = "launch successful"
	
func  _on_review_flow_failure():
	%TestLabel4.text = "launch fail!"

Finally - when the conditions are met I call for the in-app review like so:

inapp_review.generate_review_info()

When running the code I don’t get any crashes, but I get these warnings in the Debugger:

The signal “review_info_generated” is declared but never explicitly used in the class.
The signal “review_info_generation_failed” is declared but never explicitly used in the class.
The signal “review_flow_launched” is declared but never explicitly used in the class.
The signal “review_flow_launched_failed” is declared but never explicitly used in the class.

So I think how this is supposed to work is that after I call inapp_review.generate_review_info:

the call goes out to plugin inapp_review object to generate the review
If successful, the object sends a signal back “review_info_generated”
If unsuccessful, the object sends a signal back “review_info_generation_failed”
If scene gets the signal back that is was successful, then that serves as the trigger to call inapp_review.launch_review_flow()

In my testing I never get a signal back. In my functions when I call for %TestLabel3.text to populate, it never does. And the warnings in the debugger I think confirm that the signals are never transmitted.

I have no idea what I could be doing wrong…any assist would be of great help!
