I am getting "'Promise' is undefined" error on IE 11, Chrome and Firefox are not giving this error.

I am using below package for OIDC client, I already submitted an issue to that author as well. https://github.com/IdentityModel/oidc-client-js/issues/826

If I click the link SCRIPT5009 I get directed to https://learn.microsoft.com/en-us/scripting/javascript/misc/undefined-identifier

I installed below two, the issue is still continuing https://www.npmjs.com/package/babel-polyfill https://www.npmjs.com/package/promise-polyfill

Also, I read articles on StackOverflow and on the web that promise errors come from using arrow functions and having ES6 code, but this issue is coming up within OIDC package so none of the code in the app giving this error.
