Pushover OH3

another migration problem i have,
I understand from the doc files that now a thing needs to be created, compared to previous cfg file.

Now the DOC says it should look like:

val actions = getActions("pushover", "pushover:pushover-account:account")
actions.sendMessage("Hello <font color='green'>World</font>!", "openHAB")

Does the old-fashioned way not work anymore? (huffff)
sendPushoverMessage(pushoverBuilder("..........").withTitle("ETA SH20 | Heating").withSound("bugle"))

Because for me it looks way more complex and i do not need any success feedback…is there a more simple way with a single line like before? Thanks
