Clipboard extension support on liluo.io or online servers

Well I have to come back at that:
netlify is not a game hosting platform. It’s for web applications and web sites.
Using it for your game is probably among the clumsier ways to distribute your online game.
I tested it on game-jolt. It does not work. It responds exactly the same way as itch.io.
So, it could really help developers if you let them know that the clipboard extension does not work on online gaming platforms. It would be a time saver or help them plan on publishing it mobile or desktop.

The broker server I use (I set up my own) allows for a minimum of 20 characters for the generated ID.
So I cannot set it to 4 characters to make it usable.

Do you have experience with different broker server sites?
It’s a non commercial project, so I do not want to pay for the broker site.
Are there free cloud platforms for broker servers that allow for 4 characters for generated IDs?

Yes, that was what I meant with not using IDs directly. I will try that out.

Well absolutely, that would be way more intuitive! But how is that possible? Gdevelop does not allow Text entry or text objects to allow selecting and copying the text.
Are you suggesting that I program my own text entry objects or use functionalities available directly in pixi.js?
