You´ll need to download the newest JDA.jar here:
Download JDA-5.0.0-beta.2.jar and put it in your additional libs folder. Also remember to reference it using
B4X:
#additionaljar:JDA-5.0.0-beta.2

The following code is needed in your appstart
B4X:
    Dim b As JDABuilder
    b.Initialize2(token) ' String token from Developersite
    b.setAutoReconnect(True).setEnableShutdownHook(True)
    jda.Initialize("JDA",b.build)


    Dim sh As DefaultShardManagerBuilder
    sh.Initialize("ShardManager")
    sh.setToken(token)
    sh.build
    jda.awaitReady

onReady is called when the JDA has finished initialisation and you can now use Api methods.
B4X:
Sub JDA_onReady(event As Object)
    Log($"JDA_onReady(${event})"$)
End Sub

onMessageReceived is the main-entry point for you as the Developer.
Every Message the Bot receives raises this Event. You even get Events for Message you send.
B4X:
Sub JDA_onMessageReceived(event As Object)
    Log($"JDA_onMessageReceived(${event})"$)
    Dim ev As MessageReceivedEvent = event
End Sub

onGuildMemberJoin is a Event which is raised the First Time a new User Logged in into your Discord Server.
Or better. A user Logged in into one of the Guilds your Bot has Access to.

B4X:
Sub JDA_onGuildMemberJoin(event As GuildMemberJoinEvent)
    Log($"JDA_onGuildMemberJoin(${event})"$)
    'Dim ev As GuildMemberJoinEvent = event
    Log($"GuildMemberJoin.Member ${event.Member}"$)
    Log($"GuildMemberJoin.User ${event.User}"$)
End Sub
