autocompletion not enabled on new file type, gjs,gts

[NullVoxPopuli]

reference: gjs in neovim has a filetype of javascript.glimmer gts in neovim has a filetype of typescript.glimmer

I have config to accomodate:

      require'nvim-treesitter.configs'.setup {
        autotag = {
          enable = true,
          filetypes = { 
            "html",  
            "javascript", "typescript",
            "typescript.glimmer", "javascript.glimmer",
            "javascriptreact", "typescriptreact",
            "markdown",
            "glimmer", "handlebars", "hbs", "svelte", "vue"
          }
        },

but it still doesn't work. idk if this'll be useful:
