Line numbering in text editing, OO documents ios app

Hi, OO Documents installed on iPad, iOS 16.5. App version is 7.4.
How can I turn on line numbering in text?
The app clearly manages line numbered text, as I can open odt or docx documents with line numbering and numbers are displayed. But no function to enable/disable it in the app itself.

Am I too dumb to find it?

Would be glad for help.

Best,
Velo

Hello @velo

Sorry for the late response.

We have registered your suggestion to add line numbering to Mobile App as an enhancement. I will be implemented in one of the future versions of application.
