restricting access with “members”

Hello,

I read in the FAQ that you can use “Form Manager” together with “Members” to restrict columns of the data table (https://www.campbellhoffman.com/question/how-do-i-restrict-access-to-different-parts-of-form-manager/).
What I want is for some editors to only see parts of the submitted data (in the overview as well as in the downloaded file).

I’m having trouble though:

The first thing that I find strange: Members doesn’t show any capabilities starting with “form_”. I even tried re-installing Members, no use…
So I added them manually. Then I made a new user role similar to editor and checked all the capabilities for Form Manager. However, the user with that role can’t even see the menu in the dashboard.

Also, I don’t really understand how to use the ‘Options’ box. Do I have to add more capabilities for this to work?

Thanks in advance for your help.

PS: This plugin combo is the only method I found – if you know any other ways, please let me know!
