Pushover Binding 3.2 - need help with rules

I totally lost with the migration from oh2.5 to 3.2 binding :frowning:

When switching the pushover button to on I always get this error

[ERROR] [internal.handler.ScriptActionHandler] - Script execution of rule with UID 'test-1' failed: 'sendHtmlMessage' is not a member of 'org.openhab.core.thing.binding.ThingActions'; line 15, column 17, length 78 in test

rule "Pushover Test"
    when
        Item pushover received command
    then
        val actions = getActions("pushover", "pushover:pushover-account:account")
        switch(receivedCommand) {
            case ON: {
                
                // sendPushoverMessage(pushoverBuilder("test message").withPriority(1).withSound("magic"))
                actions.sendHtmlMessage("Hello <font color='green'>World</font>!", "openHAB3")
                 logInfo("PUSHOVER", "--> on ")

            }

            case OFF: {
                 logInfo("PUSHOVER", "--> off ")

            }
        }
end

I appreciate any help…

You’ve installed the Pushover binding?

You’ve create the Pushover Thing and configured it as needed?

The Pushover Thing is showing as online in MainUI?

The second argument you’ve passed to getActions is the exact same as the ID for the Pushover Thing? It is almost certainly different from "pushover:pushover-account:account".

Indeed - I have forgotten to install the binding.
Thanks for pointing me in the right direction!
