I installed the plug-in but can't find it in Final Cut

Ensure you are looking in the correct place in Final Cut:

Video Filters such as DH_Box, DH_Dropout, DH_Fade and DH_Reincarnation appear in the Video Filters > Digital Heaven folder of the Effects Browser or Effects Menu.

Video Generators such as DH_Counter, DH_Grid, DH_Guides, DH_LegalText, DH_Subtitle and DH_WideSafe appear in the Video Generators > Digital Heaven folder of the Effects Browser or popup menu at the lower right of the Viewer.

Video Transitions such as DH_Dream, DH_FieldTrans, DH_RetroTV and DH_WhipPan appear in the Video Transitions > Digital Heaven folder of the Effects Browser or Effects Menu.
