It would be best to ask the author of the file for support. You can post a comment in the Discussion section of the file.

However, if you want help from the forum, you will have to specify what you tried and what error you encountered.

i see this example:

MyBot=telegram_bot('');
% to tune webhook you need point next variables
url = ''; % HTTPS url to send updates to
certificate_path = ''; % *.pem, your public key certificate
ip_addres = ''; % Optional The fixed IP address which will be used to send webhook requests
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%% check state of bot %%%%%%%%%%%%%%%%%%%%%%
BotInfo = MyBot.getMe;
disp('This was returned by MyBot.getMe:');
disp(BotInfo);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%% set webhook %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
MyBot.setWebhook(url, 'certificate', certificate_path, 'ip_address', ip_addres)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%% check webhok status %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
MyBot.getWebhookInfo()
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%% delete webhook %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
MyBot.deleteWebhook()

i dont know how  telegram bot works so not how to initialize those variables (url = '';
certificate_path = ''; ip_address = '';)
Maybe someone who has already used it can help me
