Multiple testing account on google action collides with state intents


Hello everyone, me with my team testing our Google action by adding a member in IAM as a viewer.
When I and my assigned(viewer-user2) start to test Google action parallelly, there is an Intent inside the state that asks the user to tell the desired number
return this.followUpState('NumberState').ask(prompt, reprompt);

when I reach above code, his (viewers) another intent state is triggered and vice versa
Instead of I expecting numbers to input as input, viewers another intent input is displayed on my testing(mobile) screen

any help is appreciable
