Hello,
New to this workflow workout, just managing my needs.
so i just used a php library(credits inside the file) to reach open subtitles api , download the sub, extract the zip and show in finder. you need to change the config file to use it for your own language settings. it's a very basic workflow. but it's helping me a lot since such a specific app is not available for mac.
btw, it sometimes takes time to show results and default callbacks are listed while it's searching, so just wait for the results. i did not look for the reason in specific, i m sure it s documented somewhere.
