We want to add a new plugin to KDE Connect, that will be used to ring your phone phone you can't find it. To start with, in this task we want to make a copy of the "ping" plugin in bot KDE and Android, but renaming it to "findmyphone_plugin" and document the process.

This task does NOT require you to implement the real "find my phone" plugin, only a stub for it, and document the process in a SIMPLE readme file. Nothing fancy, just a plain text file with the steps: 1. Copy the ping plugin under a different name, 2. Edit those files and change that to that., 3. Add the name of the plugin to these files, etc.

The plugin you add should have no visible buttons in the Android app nor in KDE, but should provide a DBus interface exactly as the ping plugin does that acts the same way as the ping plugin does (but without using the ping plugin!).

The goal of this task is that you understand how plugins are added and document all the steps required.
