Bluetooth Obex decoding not working

I'm trying to use Wireshark to understand OBEX and profiles built on top of OBEX, like PBAP. Most OBEX records are not identified as OBEX, but rather identified as just RFCOMM. And the payload is not decoded. Has anyone successfully decoded Obex transfers? Trying to force Wireshark to Decode As Obex didn't work either.

Have you looked at sample capture (and notes) attached to
8304: Improve support of MAP, PBAP, BPP and BIP in OBEX and some minor patches?

Thank you @Chuckc, that was enough to get me there. I had expected OBEX and PBAP, etc. to be automatically recognized and not need to use Decode As, but that apparently isn't the case?? My main problem was I didn't understand exactly how to use Decode As...
