SNS connector to Scaleway service fails, wish to specify the url

[qualitesys]

Describe the Bug

I need to use the SNS connector with the provider Scaleway.
The AWS SNS Connector send HTTP requests to http://sns.{region}.amazonaws.com
Scaleway expects this url https://sns.mnq.{region}.scaleway.com
The arn it formed like this : arn:scw:sns:{region}:{SCW_project-id}:{sns_topic_name}
As it is implemented in the AWS SQS Connector, is it possible to specify the url of the SNS service instead of relying on the arn definition ?
Thanks for your help
