Invite message template Cognito Terraform example

Hi All,
Does anyone know how to put the Invite message template in the script. I tried the below and it gives me the below error:
Error: aws_cognito_user_pool.admin_cognito_pool: : invalid or unknown key

invite_message_template {
email_subject = “Welcome”

FYI, i already have below and i am getting conflict error messages when running terraform plan. Any ideas how to implement this?
verification_message_template {
email_subject = “Hi there”
