Nuxt.js exchanging authorization code for access token Oauth2 - oauth-2.0

Question

I'm trying to exchange the authorization code I got in the first step of the documentation for access token. Where I'm stuck is how to send a request for the token that contains the code I've just got with the first request.
This is my code:
auth: {
redirect: {
login: '/',
callback: '/auth'
},
strategies: {
wrike: {
scheme: 'oauth2',
endpoints: {
authorization: 'https://login.wrike.com/oauth2/authorize/v4',
token: 'https://login.wrike.com/oauth2/token',
logout: '/'
},
token: {
property: 'access_token',
type: 'Bearer',
maxAge: 1800
},
responseType: 'code',
grantType: 'authorization_code',
accessType: 'offline',
clientId: XXXX,
client_secret: YYYY
}
}
}
I can't figure it out how I should set up the redirect URI, in the client or in the server side? How should I do the second request? (This below)
POST https://login.wrike.com/oauth2/token
//Parameters:
client_id=<client_id>
client_secret=<client_secret>
grant_type=authorization_code
code=<authorization_code>

I think Edward is right. It doesn't seem to work. You can either do the custom schema which is what I am going to do, or you can do what I currently have which is something like this (of course ignore all the console.log and stuff like that):
const urlParams = new URLSearchParams(window.location.search)
const code = urlParams.get('code')
const state = urlParams.get('state')
console.log('state', state)
console.log('stateStorage', window.localStorage.getItem(state))
if ((code && state) && state === window.localStorage.getItem('state')) {
this.$axios.post('http://publisher-local.co.uk:8080/oauth/token', {
grant_type: 'authorization_code',
client_id: 5,
redirect_uri: 'http://localhost:3000/auth',
code_verifier: window.localStorage.getItem('verifier'),
code
}).then(response => {
this.$auth.setUserToken(response.data.access_token)
this.$auth.fetchUser()
})
}
So basically after you are redirected back to your client after logging in on the server page just look for the details in the URL and make the request yourself.
