Which language do you translate to?
Some languages have lots of subbers, while others have none so it’s indeed possible that you have to translate it by yourself.
However, if there are other subbers working in your language, you can reach them by posting here on Discussions (specifically mention the show and the language) or on the unofficial Viki D!scord server that a lot of volunteers subscribed to.
If you know any subbers in your language, you can also message them directly. You can check on recent shows if they are subbed into your language and then look up the moderator or editor and invite them or ask them if they know any good subbers.
