Making telescope.nvim find_files show hidden files by default - Following ThePrimeagen's guide

Hey guys, I'm following the tutorial above, and in his video he doesn't do anything specific to show hidden files, but it works for him. My .config/nvim/after/plugin/telescope.lua file looks like this: I've looked up solutions but they all use a different syntax, and none work for me. Any idea how I can make the find_files command also show hidden files by using this syntax? Thanks!
