Login with Oauth2 API Invalid redirect url (4,700)

I have created my app in zoom marketplace, everything is fine. Now I try to authenticate with OAuth2, as follows:

  1. First I place a login link, with two query url params, where the CLIENT_ID and the REDIRECT_URL appear, both very well checked, the url is identical to the url of my app (The one that appears next to the install button, and the REDIRECT_URL also is included in white list, all ok) .


So far so good, the problem is that this URL only works when you have previously logged into the zoom account, and it fails when you have not logged in. The following error appears.

Please maybe I am in a misconception and it is not a problem, or is it a requirement to have a session open in zoom to authenticate?
