Is command line: -platform webgl:port=xx deprecated?

[carser]

I'm using Qt 6.3.0 with msvc2019_64 compiler.
I would like to run my application with the command line parameter "-platform webgl: port = xx", but it gives an error because webgl is not among the available platforms.
In fact in the folder: [...] \ 6.3.0 \ msvc2019_64 \ plugins \ platforms the library qwebgl.dll is not present.
-> with Qt 6.3 version it is no longer possible to launch applications with -platform webgl?
-> if yes, from which version of Qt has this been deprecated?
-> if not, how can I resolve to have the webgl platform available?

Hi and welcome to devnet,

From a quick search, QtQuick WebGL is not available at all in Qt 6 currently. See here for the comparison and explanation.

Depending on what you are developing, Qt for WebAssembly might be a possibility.
