B4J Question Recall a sub

[Isac]

how do I call a sub in a button?

Sub SendMessage(Topic As String, Title As String, Body As String)
    Dim Job As HttpJob
    Job.Initialize("fcm", Me)   
    Dim m As Map = CreateMap("to": $"/topics/${Topic}"$)

Sub Button1_MouseClicked (EventData As MouseEvent)
   SendMessage()

End Sub
