How can I use multiple accounts with Telegram?

Is there a way to have two copies of telegram app in Ubuntu each with a different account?

It seems copying the app in another folder does not work.

Update of June 2020

Telegram destop now supports multiple account out of the box:

For macOS, use the official telegram for macOS: https://macos.telegram.org/ . It supports multiple accounts out of the box.

With telegram desktop installed:

mkdir ~/.telegram2ndprofile 
telegram -many -workdir ~/.telegram2ndprofile

Source

What I do is run the Telegram binary as a different user

cd ~/Downloads/Telegram/
sudo -u otheruser ./Telegram
