The class ChiselStage is a lower-level API that you probably don't want to use directly. You likely want to use the object ChiselStage and do something like:

// To return a string:
val verilog: String = ChiselStage.emitSystemVerilog(new Hello)
// To write to a file:
ChiselStage.emitSystemVerilogFile(new Hello)

The Scaladoc for this may help you navigate available methods: https://javadoc.io/doc/org.chipsalliance/chisel_2.13/6.0.0/circt/stage/ChiselStage$.html
