thats the node tree of the system

What do you mean by "doesn't work" and "never finishes"? I copied your code into a new project, replicated the node structure and called dialog() with an array containing some strings, it displays all of them and then at the end hides the box with no issues.

Embedding code in discord messages

Inline Code

When you surround some words with single backticks like `this`, it will be formatted as code.

Code Blocks

You can also include code blocks by surrounding the code with three backticks. If you add "swift" then you will also get basic syntax highlighting:
```swift
print("hello world")
```
Discord will then show it as a code block like this:

print("hello world")

Upload

If your code snippet is rather long, you can upload it to a text paste site. One option that supports syntax highlighting for GDScript is https://bpa.st/

Also, #1235176210477355098 is for questions that are very specific, often require technical knowledge of the engine's internals, and where the asker doesn't require a walkthrough to solve the problem, only pointers or hints. This doesn't seem to fit that, you might have better luck in #1235175950241628273
