Unable to edit the nextcloud app

Hi All,

I am stuck at a point that I have no idea how to proceed further. I followed the below documentation for installation of nextcloud server using docker and wsl. I am able to run the applciation by adding any applcation in apps-extra folder. But I am not able to edit any of the app. If i do make any changes in the app, the chnages are not reflected on the application running.

What docs? You did not provide the link.

Are you trying to develop an app?
