How to add a mixin with a large nesting to the class so that the this class would be inside the functions?

Question

JavaScript

let users = {foo: {bar: {function baz() {
 this.req()
}}}}

let test = {function test() {
 this.req()
}}

class API{
 req() {
  console.log('req')
 }
}
Object.assign(API.prototype, {users})
new API().users.foo.bar.baz()//this undefined

Object.assign(API.prototype, test)
new API().test()//req

If in the mixin object immediately the functions go and add them to the class, then this works. And if there is a large investment, then no.
