Trying to get an exit delay working for the Frient Intelligent Keypad..

The quirk is defined here https://github.com/zigpy/zha-device-handlers/blob/f11926e2752b07e318c48326aceec006e1f7d8e0/zhaquirks/develco/intelligent_keypad.py#L4 but I believe ZHA as a whole does not currently allow setting any sort of delay. It looks to me that this line will always send a delay of 0 to the device:

Am I right in thinking we would need to allow a value to be set in the ZHA UI (similar to the default passcode) and then pass that value as the delay in this function?

If anyone could give some pointers on how to approach this, I would be happy to take a look
