I cannot find the next button in the Lab: Creating and Deploying an atlas cluster
Welcome to the MongoDB Community forums
Here you need to authenticate your shell with the created MongoDB Atlas cluster:
To authenticate with the shell, follow these steps:
Open the link provided in the shell: Cloud: MongoDB Cloud
Enter the one-time verification code that was given to you in the shell. (If you are not logged in - it will redirect you to log in to your MongoDB Atlas Cluster and then the following window prompt will open)
Follow the additional prompts in the shell.
Click on the Check button located in the bottom right corner to complete the lab.
If you have any doubts, please feel free to reach out to us.
