How to use Keygrip with “cookies” package to sign cookies?

Question

I'm trying to sign cookies using keygrip, also check if cookie is tampered. But unable to connect them after reading documents. For example:

server.js

const cookieParser = require("cookie-parser");
const ck = require("cookies");
const kg = require("keygrip");
const keylist = ['key1', 'key2'];
const mykg = kg(keylist);
app.use(cookieParser());
app.use(ck()); // error: app.use() requires a middleware function
const httpSServer = httpS.createServer({...}, app);
httpSServer.listen(3001, ()=>{console.log('httpS is on 3001');});

How would I use cookies and keygrip in controller1.js?

const unsigned= { httpOnly: true, sameSite: 'Strict', secure: true};
// below is for signed: false
res.cookie('myID1', 'abc123', unsigned);
