Hello @Gley Müller
Thanks for reaching out to us, with the endpoint only, you can not get access to the workspace without an invitation.
To protect the privacy, you can not see any information of the workspace if you have no access to it. You may try to connect with support team to see if they can verify your information and provide you the access, please raise a support ticket for that if you have a support plan, if you don't have a support plan, I am happy to enable you a free ticket for your issue. Please let me know.
Sorry about that.
Regards,
Yutong
