AWS Cloudshell Termination

We received an email about the termination of the AWS CloudShell but we only sure the simple storage S3. Does the AWS CloudShell affects us in any way. All the information I find is very confusing and I have been unable to find a phone number to call customer service. Just need to know if I need to worry about the AWS CloudShell being deleted since we only use the S3 simple storage service. Thank you.
