[atlas] HTTP or not HTTP?

I'm surprised to see in UDM documentation that you can do HTTP measurements: https://atlas.ripe.net/doc/udm#http-http6 But I do not find this option in the "Choose a measurement" menu of the Web interface. And it is not documented in the REST API: https://atlas.ripe.net/doc/measurement-creation-api/

type: One of ping,traceroute,dns or sslcert

So, can we do HTTP measurements with the Atlas probes?
