Endpoint Telegram Send Message not works?

Hi guys,

I have trouble with Telegram Send Message Endpoint, I followed the documentations but still it is not sending the message it supposed to do. This is (picture) my setting on platform:

and this is a part of my logic code:


        if (temperatur <= 25.00 || temperatur >= 33.00){
          thing.call_endpoint("SMAQ1_TEMPERATURE_ALERT", temperatur);

the code works, I also can see the sensor value on my platform dashboard.
I tried to warm the probe sensor until it reach 34.00, but my telegram bot not sending any notifications in designated group chat.
any help?
