How do I check in "rego" that aws arn contains both valid bucket name and object name? One way is regex match , but its not giving me valid result

Question

I am running as below :

package play

import future.keywords.if
default hello := false

arn_list := input.message
hello if {
regex.match("aws:arn:s3:::.*/*", arn_list)
}

arn_list is {
"message": "arn:aws:s3:::my_corporate_bucket/ram"
}

I tried regex.match , Still I am not getting valid result.
