Solution
1) To find the interfering/Neighbor FortiAP, we need to enable FortiAP scanning in WIDS-profile as below.

# config wireless-controller wids-profile
    edit "profile-name"
        set ap-scan enable                         <----- Enable AP-SCAN.
    next
end

2) Map the configured WIDS-profile to the WTP-profile to which FortiAP is configured.

# config wireless-controller wtp-profile
    edit "WTP-profile_Name"
        # config radio-1
           set wids-profile "wids-profile_name"
        end
        # config radio-2
           set wids-profile "wids-profile_name"
        end
    next
end

3) Now, find the Interfering/Neighbor FortiAP on the FortiAP by executing the below command on the FortiAP CLI is possible.

FAP# cw_diag -c ap-scan
