How do I install Trakt on Plex on my QNap NAS?

Hello,
I have a QNAP NAS model TS-869 PRO, can you tell me which file I have to download? I already installed the QNAP-wt-Install icon on my NAS, I want to install the TRAKT scrobbler, but which file do I choose?
I only see Synology and Drobo as NAS options to install to on the github page:

Thanks in advance
