Partner center Get Bearer access token

Question

Dears,

I want to use swagger API, I want to test some partner API requests. However, the swagger is not working. I am getting the error displayed in the below image status 401.

Do I need to generate another token?

I used the token generated when I log in with the account in swagger.

Is the error based on the token or a permission for the account?
