How to record "telegram node" updated data

In my case:
I use telegram node with reply keyboard
Now I want to use selected replies by my users.

Note: By “telegram trigger” I can use previous selected reply, but I want to know how to save and use saved replies. I tried to save variable by “Set node” but It is cleared after per update on “telegram trigger”

You can use a Merge-Node for that. Simply place it in front of the “Menu”-Node above and then add the lower Set-Node as a second input. You should probably use mode “wait” or “pass-through”.
