Client ID undefined in initTokenClient call

Question

I need to acquire access token for accessing google sheets api. This is a code inside Next.js page, which is also denoted as 'use client'. Google api library script is loaded like so:

<Script 
    src="https://accounts.google.com/gsi/client" 
    async={true}
/>

Client is being initialized in a function, that is triggered by a button press, so we can be sure, google api library has already been loaded:

let client = window?.google.accounts.oauth2.initTokenClient({
    client_id: '[CLIENT_ID].apps.googleusercontent.com',
    scope: 'https://www.googleapis.com/auth/spreadsheets',
    callback: onSignIn,
    auto_select: true,
})

But when window?.google.accounts.oauth2.initTokenClient is called, i get an error in the console:

When i inspect the network tab, i can see that the client_id is not being passed on:
