Elasticsearch templates

I notice that starting from elasticsearch 8.x everything has changed in relation to working with templates and I am very confused and I would like a Samaritan to help me solve this problem.

curl -s -H "Content-type: application/json" -X PUT -u elastic:password https://127.0.0.1:9200/_template/scan -d'

  "template": "scan-*",
  "settings": {

    "index.refresh_interval": "5s"
  },

      "_all": {
        "enabled": false
      },
      "properties": {
        "@timestamp": {
          "type": "date",
          "format": "dateOptionalTime"
        },
        "@version": {
          "type": "integer",
          "index": "not_analyzed"
        },
        "time_t": {

              "type": "geo_point"
            }
          }
        }
      }
    }
  }
}'
