Update exsiting Azure App Service in Terraform

I would like to update my exsiting Azure App Service in Terraform by adding a Backup to this App Service.
For now it looks like this:

data "azurerm_app_service_plan" "example" {
  name                = "MyUniqueServicePlan"
  resource_group_name = "example-resources"
}


resource "azurerm_app_service" "example" {
  name                = "MyUniqueWebAppName"
  location            = "West Europe"
  resource_group_name = "example-resources"
  app_service_plan_id = data.azurerm_app_service_plan.example.id


  connection_string {
    name  = "myConectionString"
    type  = "SQLServer"
    value = "Server=tcp:mysqlservername123.database.windows.net,1433;Initial Catalog=MyDatabaseName;Persist Security Info=False;User ID=xxx;Password=xxxxxx;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"
  }
  backup {
    name                = "MyBackupName"
    enabled             = true
    storage_account_url = "https://storageaccountnameqwetih.blob.core.windows.net/mycontainer?sp=r&st=2022-08-31T09:49:17Z&se=2022-08-31T17:49:17Z&spr=https&sv=2021-06-08&sr=c&sig=2JwQ%xx%2B%2xxB5xxxxFZxxVyAadjxxV8%3D"
    schedule {
      frequency_interval       = 30
      frequency_unit           = "Day"
      keep_at_least_one_backup = true
      retention_period_in_days = 10
      start_time               = "2022-08-31T07:11:56.52Z"
    }
  }
}

But when I run it i got a error A resource with the ID ........ /MyUniqueWebAppName" already exists - to be managed via Terraform this resource needs to be imported into the State.
How in terraform can I point to an existing Azure APP Service and add a backup with the same schedule as I did in my template?

    Before you can modify your existing resources with TF, you must import into the terraform state. For this you use import command.

        data "azurerm_resource_group" "example" {
         name = "<give rg name existing one>"
}

    data "azurerm_app_service_plan" "example" {
      name                = "MyUniqueServicePlan"
      resource_group_name = data.azurerm_resource_group.example.name

        schedule {

          keep_at_least_one_backup = true
          retention_period_in_days = 10
          start_time               = "2022-08-31T07:11:56.52Z"
        }
      }
    }

    No need to use import command , use this code for your reference
    just give rg name existing one in resources group block
