How can I type the this argument when my function receives it?

import { generatePath } from 'react-router-dom';

type generatePathParamsType = Parameters<typeof generatePath>[1];

// Following type definition of 'this' is not working
const generatePathFactory = function (this: typeof ENV_DASHBOARD) {
  return function (args: generatePathParamsType = {}) {
    // 'this' implicitly has type 'any' because it does not have a type annotation.
    return generatePath(this.PATH, args);
  };
};

const ENV_DASHBOARD = {
  PATH: "/dashboard/:environmentId",
  generatePath: generatePathFactory.apply(this),
  TITLE: "Dashboard"
};

console.log(ENV_DASHBOARD.generatePath({ environmentId: "1" })); // '/dashboard/1'
