User: arn:aws:iam::72440395655461:user/dynamodb-training is not authorized

i type serverless deploy and appear this error:

ServerlessError: User: arn:aws:iam::7244035466931:user/dynamodb-training is not authorized to perform: cloudformation:DescribeStacks on resource: arn:aws:cloudformation:us-east-1:724403956931:stack/primerProyectoSLS-dev/*

it seems like the user dynamodb-training does not have access to the cloudformation service. I will create a new IAM role and add the user to the role.
