Set HttpOnly Tag Cookie

Hello,

I want to set Cookie attribute SameSite=none to use cookie in iframe. As I have researched, I have to set Cookie SameSite on the server-side because it is HttpOnly Tag. Therefore, I want to setCookie on serverless app, however, I don’t know how to do it. How to set Cookie HttpIOnly Tag in serverless app?

Thank you very much
