Rasa chatbot Multiple buttons selection with Telegram

Hi again !!! I just want to know the possibility of adding multiple buttons in Rasa bot for telegram. I want to allow user to select multiple options from buttons same time. Then a list of selected options should be stored in the slot list. Is it possible with Telegram ?

Ex: Select all the symptoms you have.

  • Button_1 - Fever :white_check_mark:
  • Button_2 - Cough
  • Button_3 - Fatigue :white_check_mark:
  • Button_4 - Headache :white_check_mark:

User will select two or three symptoms and click submit button finally.

Expected result - [Fever, Fatigue, Headache]

I implemented this with Rasa 3.0 but I got an empty list []. When I select a few buttons and click on submit button, no value is stored in the slot list. I noticed the same question in the forum saying that Rasa supports only for single choice from buttons list. I want to know is it possible with Rasa 3.0 ?
