OAuth2 client credentials don't working at portal

[andrewshytiy]

Hello everyone! I have trial Edge license and Edge (4.19.06) at Private cloud. I have problem with OAuth2 (grant_type=client_credentials) on the portal (7.69). I install smartdocs_oauth_additions module and enable it. I set up OAuth2 security scheme for my model.

Here I don't fully understand the difference between authorization and access token url.

If I go to the portal in any method of my model on the portal and press the OAuth2 button, I see a form in which I can not enter a consumer ID and secret.

After clicking OK, I get an error:

"Unable to proceed because of missing OAuth configuration."

What I did not consider when setting up OAuth2?

I would be grateful for practical advice.

Thanks.
