I'm Having Problems with the Functions in the Widget API Section in the Wix Blocks Application

Question:
Is it possible to get the value from a function in the functions section of the application panel without using parentheses?

Product:
Wix Blocks

What are you trying to achieve:
I have Function code in Wix Blocks as follows:
/** (I had to put a space. The forum was giving an error.)

Here I tried to create a function that stores data in a repeater.

I installed the application on my website and wrote the following code (User Panel):
Ekran görüntüsü 2024-08-29 201946

Console result:
Ekran görüntüsü 2024-08-29 195753

There are two problems here:
1 - We can only retrieve data as long as we use parentheses.
2 - Nothing I type in the application panel appears here. And he says ‘any’ to everything:

What have you already tried:
I’ve done almost all the things that can be tried with ‘@returns {}’. However, I still could not achieve the result I wanted. Also, it’s too bad that the function description I wrote in the application panel is not visible and everything is called ‘any’.

Additional information:
The only thing I’m trying to do is: get the data without using parentheses. For example, we write the following code to access data on a repeater:
$w.(‘#repeater’).data;

The user should get exactly like this in the code panel:
$w(‘#APP’).messageContent;

However, unfortunately, it can currently only be retrieved using parentheses.

Please help me on this. If such a thing is not possible, please consider adding this feature. I would also like to know the reason why the function description is not visible in the user panel.

Thank you for your interest. I will be waiting for an answer from someone knowledgeable or authorized on this subject.
