Connection to Home Connect appliances

Has anybody tried to connect to Home Connect appliances? They have an impressive API with a complete module for testing in Postman, but I am having a hard time finding how to connect to an apliance with the right authorisations.

Actually I found out that when authorising an app in “Home Connect API” ( you do not have to select any permission, the process will do it for you. You can test the commands in that page or in Postman (make sure all the variables are correctly set and add accessToken and haid if you are using the “API client - Physical Home Appliances”.
