I have tried doing that on the server using a text object and it works. you do not need an extension for this.
Go to: http://<Server name>/single (Dev Hub) -> select your app -> select your sheet and copy the URL.
Select the text in the text object in your App and add a hyper link to it and it should work
On Desktop edition, it opens the sheet in a web browser.
This the URL for the desktop version: http://localhost:4848/single
Hope this solves your issue
