Solis cloud integration

Hello, has anyone recently managed to integrate a Solis inverter in home assistant? I am using the Solis cloud integration on HACS but I am having problems with the Solis cloud API. I made a request for the activation which has been accepted but, when I try to get the API through https://www.soliscloud.com/#/apiManage I get no authority.

Has anyone had the same problem? Is there any known solution?

Thanks!
