With Tauri how can i save a file to a specific path?

I have this code:

async function downloadMod(url, folder, basePath) {        const httpclient = await getClient();        const file = await httpclient.get(url, {          responseType: ResponseType.Binary        });        invoke("expand_scope", { folderPath: basePath }) // Used to allow writes in whatever folder i want        await writeTextFile( url.split('#')[0].split('?')[0].split('/').pop(), Uint8Array.from(file.data), { dir:  BaseDirectory.Desktop });}

How can i save the file to basePath + folder and if basePath's folder folder dosent exists create one?

Im on windows btw...

I tried using the string as the path but it didnt work, it didnt spit out an error but didnt create the file...
