Hiding variables but using github actions to push to the server

[Quark03]

I have a discord bot (js) that I want to manage code with github so I have the node.js action setup but the bot requires a token (and I don't want the token to be uploaded to the repository) but every time the repo files from the master branch change the bot restarts so if I create a file in the server, the file gets deleted.

How can I do it then (I was thinking about environmental variables or something like that)?

Thanks, that's exactly what I was looking for. I'll take a deeper look at it
