Android Question Firebase messages arrived

[DestroShark]

Hello
Faced such a problem that by sending a message to a specific topic from one device, the message is displayed in any topics(which both devices are subscribed). The problem is in the function fm_MessageArrived I call the method in the function to display messages, how can I display them in only one topic? I would be very grateful if anyone can help me.

Sub fm_MessageArrived (Message As RemoteMessage)
    Log("Message arrived")
    Log($"Message data: ${Message.GetData}"$)
    Dim n As Notification
    n.Initialize
    n.Icon = "icon"
      
    Dim strArray() As String =Regex.Split(";",Message.GetData.Get("title"))
  
    n.SetInfo(strArray(0), Message.GetData.Get("body"), ChatMainMenu)
  
  
    If chatex.myMail = strArray(1) Then       'strArray(1) - contains mail
        CallSub3(chatex,"myMessageArrivedOnChat",strArray(1),Message.GetData.Get("body"))
    Else if chatex.myMail <> strArray(1)Then     'strArray(1) - contains mail
        n.Notify(1)
        CallSub3(chatex,"AnotherMessageArrivedOnChat",strArray(1),Message.GetData.Get("body"))
    End If
  
End Sub

Best regards

Hello, Erel
output is "body=my message, title=name,mail"

You can get it with Message.From. It will return /topics/<topic>

Send the topic name with the message and "draw" the message only if the name of the sent one matches the name of the open topic? Did i inderstand you correctly?
Sorry for my english

You can find the topic using Message.From. Add any logic that you need based on the topic.
