Cant log in to app after deployed on Cloud Run

I have deployed my doccano app on Cloud Run but cant cant log in. It keeps complaining about the "Incorrect username or password"

enter image description here

I think this is because I havent given the auth argument, on my local I usually need use to start the container with this kind of cmd:

docker container create --name doccano 
  -e "ADMIN_USERNAME=admin" 
  -e "[email protected]" 
  -e "ADMIN_PASSWORD=password" 
  -p 8000:8000 chakkiworks/doccano

But I dont know where on GCP Cloud Run where can I add such information enter image description here

can someone help? Thanks!
