Code verifier

[GenaAiv]

I am trying to use this library but it is not very clear if the CodeVerifier works automatically, or if you gotta turn it on somehow?

Hi @GenaAiv - Looking through the tests, I think you need to add a call to .generateCodeVerifier() when defining your service.

apps-script-oauth2/test/test.js

Lines 508 to 513 in 67cae40

	var service = OAuth2.createService('test')
	.setAuthorizationBaseUrl('http://www.example.com')
	.setClientId('abc')
	.setClientSecret('def')
	.setCallbackFunction('authCallback')
	.generateCodeVerifier();

Probably a good idea to add some information about PKCE support to the README though.

I had that but it did not seem to work at first. Looks like it does work now.. I had an issue with code_verifier not being sent in the token request, which was required.. but after i copied the script locally it seem to work again
