How do I annotate an imported global?

I have the following use case. There's a library that defines a global vim.g as table<string, any>. In my application code, I want to utilise only the "autoformat" key of that table, i.e. vim.g.autoformat. I want to enforce this key as a boolean? but the language server marks it as any.

Is there any way I could achieve this?

未指定任何原始檔案、測試或進入點。首先重現 issue 中描述的 vim.g.autoformat 註解案例，並追蹤語言伺服器如何為匯入的全域變數和表格欄位判定型別。完成的標準應是確認一種受支援的方法，並提供涵蓋率或文件，說明如何將 autoformat 強制為 boolean?。
