how to setup cookie if access refly with domain

I prepare 3 domain for refly:

• refly.example.com
• reflyapi.example.com
• reflyws.example.com

environments configuration:
api:

• ORIGIN=refly.example.com
• STATIC_PUBLIC_ENDPOINT=https://reflyapi.example.com/v1/misc/public
• STATIC_PRIVATE_ENDPOINThttps://reflyapi.example.com/v1/misc
  web:
• API_URL: https://reflyapi.example.com
• COLLAB_URL: https://reflyws.example.com
• STATIC_PUBLIC_ENDPOINT: https://reflyapi.example.com/v1/misc/public
• STATIC_PRIVATE_ENDPOINT: https://reflyapi.example.com/v1/misc

remove the /api and /collab location in the nginx.conf file

How to setup below environemnts?

• AUTH_SKIP_VERIFICATION: ${AUTH_SKIP_VERIFICATION:-false}
• REFLY_COOKIE_DOMAIN: ${REFLY_COOKIE_DOMAIN:-refly.example.com}
• REFLY_COOKIE_SECURE: ${REFLY_COOKIE_SECURE:-true}
• REFLY_COOKIE_SAME_SITE: ${REFLY_COOKIE_SAME_SITE:-}
• LOGIN_REDIRECT_URL: ${LOGIN_REDIRECT_URL:-}

The current issue is the refly failed to access the /convas after login.
Please kindly advice, thanks.

Start with the nginx.conf changes and the API/web environment settings listed in the issue, especially the cookie, redirect, and endpoint variables. Reproduce the login flow with the three domains and inspect why /convas is unavailable after login. Done means the documented configuration allows access to /convas after authentication.
