Can't enable ofx in aqbanking

I installed Gnucash with variants quotes, hbci, and ofx enabled. I enabled the ofx variant in aqbanking. When I open the AqHBCI wizard in Gnucash, there is no aqofxconnect backend. I do have the backends for aqdtaus and aqhbci, but nothing that looks like it will work with ofx. Any suggestions for getting the ofx backend working? Thanks.
