Streaming DDJ - SZ

HI.  Has anyone set up streaming with OBS using an SZ?  I read the article about using Blackhole with the DDJ-1000 SRT. I already installed blackhole, soundflower and loopback but nothing worked well. I tried rekordbox 5 and 6 but also nothing happened. I followed this tutorial strictly on it's terms (https://forums.pioneerdj.com/hc/en-us/articles/360019934592-Streaming-with-OBS-DDJ-1000-Mac-). In step 4 where it is marked in red, it does not appear in my rekordbox, while i'm configurating.

I don't know what else to do to make this configuration work.

My sistems

1- MacOs Catalina (update)

2- DDJ-SZ (update)

3- Rekordbox 5 our 6 (activated)

Please Help !
