Add a feature to get the AWS S3 Bucket name of Supabase Storage

[hacking-impossible]

Hello.
I am using the Cloudmailin to catch the email and upload email attachment to Supabase Storage.
But cloudmailin support only upload files to the AWS S3 and Google Cloud Storage.
To set the cloudmailin, I need the s3 bucket name, but I can't get it from Supabase Settings.
If anyone experienced in this field, please let me know as soon as possible.
