Trigger on new Device (new DHCP Client)

### Problem Description
i would like to get a trigger for a new device connecting to the adguard dhcp server like "new device found! mac: XXX ip: XXX".

### Proposed Solution
something like a IF THIS THAN THAT / MQTT option for adguard triggered by events like a new dhcp client.

### Additional Information
i am building a smarthome and we have a lot of gadets. i like to use adguard as dhcp and want to give static ips, different filterlists and stuff like this to every client. right know its a bit stressful to find the real world clients and i would like to connect one client, get the infos (ip and mac) pushed and make the configs on my pc after i installed everything.
