Way to edit accessibility service settings?

When using apps such as Simple Control (for on screen back button) or Circle Sidebar, they require you to enable an option in the accessibility settings. I would like to enable the setting for the app so I can use them, but I do not see any options.
I saw a video on the round android smartwatch yt channel on the KOSPET hope using the simple control app.
I found another post a over a year ago asking the same question on XDA and said to look here. I haven’t found anything here though. Any help?
Here are some images that the other post provided imgur.com/a/4rzQV
I am using the LEM5 Pro.
Thank you. 

Try quick shortcut app, it’ll revealed all burried settings that normally exist
