NextCloud 20 video converter v1.0.0 overwrite option is missing


I use Nextcloud 20.0.7. Thank you very much for it.

Within my nextcloud I have the video converter app running (v1.0.0). The app says it has a feature to optionally overwrite the original file. However, I am unable to find this option in the conversion menu.

The menu I see is also different from the screenshot with the app. I have attached a screenshot for your reference.

Do I have any settings to adjust in nextcloud to see the overwrite option?

I am converting .mp4 files to .webm files.

Thank you in advance for the inputs.
