Error when configuring okta authentication

[ManiWCS]

Hi guys,

I'm trying to set up the Okta authentication following the documentation  .

I use the Customer Identity Cloud instead of Workforce identity cloud. I don't know which one to choose as I don't really know okta.

Here are the informations that I have in my okta console after creating the application:

And I left the other fields with the defaults values

Then I pasted the same client ID, domain and client secret in the AppSheet's configuration page.

But I got this error when I'm trying to connect to my app:

I need some help to figure out the problem here.
