+       etag                 = (known after apply)
+       id                   = (known after apply)
+       role                 = "member"
+       username             = "input"
    }

  # github_team_members.repo_team_members["drf-excel"] will be updated in-place
!~  resource "github_team_members" "repo_team_members" {
        id      = "drf-excel"
#        (1 unchanged attribute hidden)

+       members {
