In order to be able to copy an ID number, you need to have Developer Mode enabled. Here’s how.
- 
Tap on the cogwheel in the bottom left corner of the desktop app to open up your User Settings.
 - 
Then head to Advanced.
 - 
Now, tap on the main toggle next to Developer Mode to enable. A “checkmark” means it’s enabled, while an “x” means it’s disabled.
 
To find a Server ID number:

Telegram
- 
Login to Telegram web app.
 - 
Open the chat you want to get its ID.
 - 
Your browser’s address should look like https://web.telegram.org/a/#-1234567890.
 - 
Remove the scheme, the hostname and the path, keeping the anchor so your result looks like #-1234567890.
 - 
Replace “#-” with “-100” so it looks like -1001234567890.
 - 
You can now use your final result which should look like -1001234567890.

Your workspace ID is the string beginning with T.
