Trouble with OAuth2 Authorization supplying JWT token

Hi,

I would like to configure the same as Arno_Kobarg_623. However, we don't know how to configure postman to include the username and password in the payload to authenticate on the F5 logon page and afterwards include an authorization code to receive the JSON JWT.

I can select Type Oauth 2.0 in Postman and fill the client secret and ID but afterwards I see the logon page, where I would like to include the username and password instead of filling the logon page.

Thanks!!
