Unable to add a command that handles web_app_daa about core HOT 2 OPEN

I've not looked deeply into this yet, but since that data gets passed via a message, you should be able to get it inside your GenericmessageCommand class. Have you tried this?

class GenericmessageCommand extends SystemCommand
{
    public function execute(): ServerResponse
    {
        $data = $this->getMessage()?->getWebAppData()?->getData();

        // check if $data isn't null and do something with it.
    }
}

from core.

That's what I'm doing right now.

But I think the code has an issue (not only for Web Apps.

If $type is not 'command', this line makes it so $command_tmp always contains a string with the first character in upper case, and all the other characters in lowercase (for example: 'web_app_data' → 'Webappdata').

But this line makes it so all the command handlers have a snake_case syntax (for example: 'WebAppDataCommand' → 'web_app_data').

That way, when $type !== 'command', we'll NEVER have a match between command names derived from messages and command classes here.
