OFX Plugins not appearing in Resolve 17.1

Hello, I feel like I must be missing something really obvious. I can't get my third party OFX plugins to appear in Resolve on the edit, colour or fusion pages. I'm using 17.1 on an M1 Mac, and I know the plugins are installed correctly because in 'preferences > video plugins' they are all listed and say 'loaded successfully'. I've scanned through all instances of OFX in the manual, and still can't figure this out. Any help will be hugely appreciated! Thanks in advance.
