How to use permission in server-side with node-appwrite

export async function GET() {
    try {
        setToken();
        const userId = headers().get("x-user-id")!;

        const boards = await appwriteSDK.databases.listDocuments(
            DB.id,
            DB.collections.BOARDS_ID,
            [
                Permission.read(Role.user(userId))
            ]
        );

        return NextResponse.json(boards);
    } catch (error) {
        return NextResponse.json({ error });
    }
}

export async function POST(request: NextRequest) {
    try {
        setToken();
        const board = await request.json();
        const userId = headers().get("x-user-id")!;

        const saved = appwriteSDK.databases.createDocument(
            DB.id,
            DB.collections.BOARDS_ID,
            ID.unique(),
            board,
            [
                Permission.read(Role.user(userId))
            ]
        );

        return NextResponse.json({ saved });
    } catch (error) {
        return NextResponse.json({ error });
    }
}
