I have all the parts mentioned in the text except for <PORT>.

It's the port from this line:  ServerTransportListenAddr obfs4

0.0.0.0:<port> where the odfs4 is listening.

Right. Or if you didn't set a ServerTransportListenAddr line in your
torrc file, then you can get it either from the log line:

[notice] Registered server transport 'obfs4' at '[::]:46396'

or from a corresponding line the 'state' file in your DataDirectory.
