I need to get expiry date of a group access token , found this API in documentation but I am getting 401 in response, can you please help.

curl --header “PRIVATE-TOKEN: ” “https://gitlab.example.com/api/v4/groups/534/access_tokens/”

HTTP 401 can mean that the private access token sent for client authentication does not have the required permissions on the group level. Or that the group access token ID does not exist. Group access tokens API | GitLab
