It's almost a whole day I'm digging in google, moodle, github and nexcloud forums to just find a solution for my problem.
I have configured all setting mentioned in Moodle documentaion to have a nextcloud repository in my moodel.
Here are the screenshots:
As you can see from above screenshots, all setting were done. Hoever, I don't see the "Nextcloud Option" in File Picker neither in text field nor in assignment upload field.
I'll be so grateful if someone help to solve this annoying issue. Thanks in advance.
