B4J Question JTELEGRAM BOT(ERROR)

[slo001]

Hello
I wanted to use ui mode to use [BETA] jTelegramBot library but it gives the following error(jdk-16):

src\b4j\example\main.java:6: error: package javafx.application does not exist
public class main extends javafx.application.Application{
                                            ^
1 error
only showing the first 1 errors, of 6 total; use -Xmaxerrs if you would like to see more

javac 16

and javac 1.8.0_281 error :

src\b4j\example\main.java:45: error: cannot access JTBwrapper
public static de.donmanfred.JTBwrapper _v5 = null;
                           ^
  bad class file: C:\Program Files (x86)\Anywhere Software\B4J\libraries\jtelegrambot.jar(de/donmanfred/JTBwrapper.class)
    class file has wrong version 55.0, should be 52.0
    Please remove or make sure it appears in the correct subdirectory of the classpath.

An other problem before
When using the message editing method, it gives the following error:

my code :

deletemsg = buttons.MessageId
fron = from.Id

jtb.editMessageText(jtb.byId(fron),deletemsg,Null,"se","HTML",False,Null)
