reply markup Telegram in webhoock ifttt

Question

hello sorry but I can not understand how it works. On make integromat, the function is already included in the telegram bot, while I wanted to do the same with Iftt Online I found only the guide to send message on telegram with webhoock, but I can not find anything that tells me what code to enter for reply markup S no beginner I hope you understand thank This is the text entered to send message:

???? < button > Testo del pulsante < /button >

{{EntryUrl}}/start < a href={{EntryUrl}} > Leggi di più... < /a >

I do not know if it is so but I think that just add a code for the reply markup button to this code
