Expose udp port for play /akka?

[sejensen]

Hi is it possible to configure a udp port to be exposed,

It fails if I add it to the config in build.sbt due to types (not Int) dockerExposedPorts := Seq(9000,9008/udp)

I Found out that native packager has an update where you can specify exposed udp ports, but since this plugin relies on an old version this is not possible. Is this plugin abandoned and / or is there alternatives?

Thank you in advance Steffen
