How to write an update in the same thread on Moday

Hi,

I’m looking for a way to create an update using make when I receive a message from twillio.

I found out how to write the update but when I answer the update in monday and then I reply from my phone the new update is always put as a new one and I want to write the update in the same thread.

Here is an image of what I’m saying

Thanks in advance for your help.
