Make the app work under a proxy environment.

Currently, this app does not work on networks that connect to the outside world through proxy servers. Download the Asana App for Mobile and Desktop • Asana
Asana can be used in your browser, but you’ll still need to log into your proxy server before using it. However, it is good to launch the browser and do it once at the beginning. Rather than using Asana on a browser, this is a setting that allows the browser app to connect to the outside world.
In addition, in the case of other companies’ apps (eg Acrobat, etc.), it is necessary to log in to the proxy server when starting each app. I am attaching a screenshot.

From the above, recreate the Asana app to connect externally via a proxy server.
