Is it possible to set up such a system?
Is it possible to add a function that allows people to only see the email addresses of people with the same affiliation?
For example, people are divided into Groups A, B and C. People in Group A can see the email addresses of people in Group A, but not those in Groups B and C.
Group A people → ○ Group A people’s email address | × Group B and C people’s email address
Group B people → ○ Group B people’s email address | × Group A and C people’s email address
Group C people → ○ Group C people’s email address | × Group A and B people’s email address
