Hi, I have started and published under agpl 3.0 license a technical demo app for tracking contacts with dp3t protocol (it is a hybrid clone of their native app), I have also created a plug-in for capacitor that allows you to use their sdk . The starter uses ngxs for internal memory. the source is here (it’s an initial alpha phase):
the source of the capacitor plug-in is located here and is released under the mpl 2.0 license (at this time it only partially works on Android):
Here is a video demo:

Feel free to use it as a starting point for apps in your country and / or to help me to complete the first production release
