I've been going the new dataset type Tabular, but I'm having a hard time to find how to choose a column from a Tabular dataset
For instance, let's assume you have the following tabular dataset

test = Tabular[{<|"location" -> "study", 
      "temperaturesensor" -> "SHTC3"|>, <|"location" -> "basement", 
      "temperaturesensor" -> "BME280"|>, <|"location" -> "familyroom", 
      "temperaturesensor" -> "BME280"|>, <|"location" -> "Study", 
      "temperaturesensor" -> Missing["NotAvailable"]|>, <|
      "location" -> "DiningRoom", "temperaturesensor" -> "MCP9808"|>, <|
      "location" -> "upstairs", "temperaturesensor" -> "MCP9808"|>, <|
      "location" -> "Thermostat", "temperaturesensor" -> "DPS310"|>, <|
      "location" -> "FamilyTV", "temperaturesensor" -> "TMP117"|>, <|
      "location" -> "Indeterminate", 
      "temperaturesensor" -> "BME680"|>, <|"location" -> "LaniStudy", 
      "temperaturesensor" -> "BME680"|>, <|"location" -> "Basement", 
      "temperaturesensor" -> "BME680"|>}];

Let's assume you would like to assign or select only column location, how do you this?
I tried test["location"] like one does in Dataset, but it didn't work.
I tried test[["location"]] still did not work
and other approaches with no success.
Any help will be appreciated
