How do I updated a CloudWatch Synthetics Canary layer version number using the AWS CLI?

Hello,

I created a CloudWatch Synthetics Canary via a console blueprint

I want to update the active layer version ("39" – bolded below) using the AWS CLI

I see it in the Code["SourceLocationArn"] attribute in my describe-canary response

The update-canary operation doesn't have a SourceLocationArn option for the --code value.

How do I updated the layer version number using the AWS CLI?

Thank you
