Access denied when use "mapps code:push"

hi there ,

I’m setting up an integration for the first time. I follow the steps described in welcome-apps/apps/quickstart-integrations-monday-code at master · mondaycom/welcome-apps · GitHub. I configure the token, then when I execute “mapps code:push” I get the :heavy_multiplication_x: Access denied warning. I don’t know how to fix it, if someone helps me, I’d really appreciate it.
