Terraform plan for members

Plan: 1 to add, 1 to change, 0 to destroy.

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
+   create
!~  update in-place

Terraform will perform the following actions:

  # github_membership.this["riconnon"] will be created
+   resource "github_membership" "this" {
+       downgrade_on_destroy = false
+       etag                 = (known after apply)
+       id                   = (known after apply)
+       role                 = "member"
+       username             = "riconnon"
    }

  # github_team_members.org_designers_team_members will be updated in-place
!~  resource "github_team_members" "org_designers_team_members" {
        id      = "14084892"
#        (1 unchanged attribute hidden)

+       members {
+           role     = "member"
+           username = "GODSPE1"
        }

#        (14 unchanged blocks hidden)
    }

Plan: 1 to add, 1 to change, 0 to destroy.
