Unkown lookup type loadingLookup when using druid-lookups-cached-single

Description

I enabled the core-extension druid-lookups-cached-single and then I tried to create a new loadingLookup which should be provided by the extension. I first noticed that I could not pick the loadingLookup as the type in the console. I then used JSON instead with the following config:

{
   "type":"loadingLookup",
   "dataFetcher":{ "type":"jdbcDataFetcher", "connectorConfig":"jdbc://mysql://localhost:3306/my_data_base", "table":"lookup_table_name", "keyColumn":"key_column_name", "valueColumn": "value_column_name"},
   "loadingCacheSpec":{"type":"guava"},
   "reverseLoadingCacheSpec":{"type":"guava", "maximumSize":500000, "expireAfterAccess":100000, "expireAfterWrite":10000}
}

Which results in "Unkown lookup type loadingLookup".

The above config is taken from the documentation of the extension: https://druid.apache.org/docs/latest/development/extensions-core/druid-lookups/

I have also adjusted the dataFetcher config in the example above for my database but I don't think that makes any difference here as the type loadingLookup just doesn't seem to be present.

I can see the extension being present in the console, as shown in the screenshot below
