How to manually change translation?

[felixmaker]

For now, I only know how to init translations:

fn main() {
    slint::init_translations!(concat!(env!("CARGO_MANIFEST_DIR"), "/lang/"));
}

How to manually change translation? If the user wants other translation.

We haven't implemented that yet, but we have plans to do it.
I've just filled an issue to keep track of it: #3715
