The code with the issue can be found here: src/window.rs#L222

[margual56]

That code is based on the rfd example

[margual56]

A new attempt has been done in commit 17c351a1ced79f, with the functionality to download a modified file.

However, I cannot make it upload files because the function needs to be asynchronous, which makes the self reference to not live long enough, thus making impossible to update the attributes in self.
