Vue how to properly use JWT?

Question

Vue.js

Good afternoon.
Can someone tell me how to use JWT correctly?
Who speaks through interception, who through Vuex.
What is the best option?
generate JWT in login function

const token = jwt.sign({
                email: isUser.email,
                userId: isUser._id
            }, keys.jwt, {expiresIn: 3600})

            res.status(200).json({
                token: `Bearer ${token}`
            })

How can I properly check for authenticity, can anyone tell me?
And how to send it correctly via Vuex or Header?
