coap: Use published tools instead of custom Python script

 * Run on any board with networking, eg. `laze build -b particlex-xenon run`.
 * [Set up networking](../README.md).
-* Run `./fauxhoc.py`. This will establish a secure CoAP connection using EDHOC and OSCORE,
-  and show some interactions and eventually the log of the device.
-* Running multiple concurrent `./fauxhoc.py` instances is supported,
+* Run `pipx run coap-console coap://10.42.0.61 --credentials client.diag`,
+  which establishes a secure CoAP connection using EDHOC and OSCORE,
+  and shows the log of the device.
+* Run `pipx run --spec 'aiocoap[all]' aiocoap-client coap://10.42.0.61/.well-known/core --credentials client.diag`
+  to show what else the device can do.
+  If you kept the log running, you will see that every new command runs through EDHOC once:
+  aiocoap does not currently attempt to persist EDHOC derived OSCORE contexts across runs.
+* Running multiple concurrent terminal instances is supported,
   up to the maximum number of security contexts that are stored (currently 4).
+* There is also `./fauxhoc.py`, which did EDHOC manually before it was integrated in aiocoap.
