Note: This function works with the same parameters 
as the https://core.telegram.org/bots/api#sendmessage api, 
but you can also use another parameter of the same api, 
for example: https://core.telegram.org/bots/api#sendphoto just run it as follows:

checkchat(method="sendPhoto", chat_id=884431779, photo="https://img.olhardigital.com.br/uploads/acervo_imagens/2020/04/r4x3/20200423030657_660_495_-_python.jpg", caption='<b>ping</b>', parse_mode='HTML')
