Using DJI Go 4 on WiFi with the Polar Pro Katana Can't connect

[tradespecific]

Good Day,
Am trying to use my Polar Pro Katana tray with my Mavic. Switched to WiFi am trying to use DJI Go 4 app. The app is asking for a password. I have tried my password for my Mavic (during set up) and tried my old DJI password and they did not work. What password is the app looking for ??

Thank You

The password is located on the arm next to the QR code or under the battery on the body of the Mavic next to the QR code with the extra type.
