How to set auth key of peripheral device by phone?

[faithself]

Thanks in advanced. The platform is nrf52832 and sdk17.0.2. I want to use phone to update static key of peripheral ble device, is there an example for this?

I've developed this function, but I use character:
"955a15270fe2f5aaa09484b8d4f3e8ad": {
"name": "Manufacturer ID"
},

because it's belong to Beacon Config service. Would any expert tell me the proper (service, charater) map used to describe passkey updating?
