 You can also provide additional options:
 ```js
 import s3 from 'k6/x/frostfs/s3';
-const s3_cli = s3.connect("https://s3.frostfs.devenv:8080", {'no_verify_ssl': 'true', 'timeout': '60s'})
+const s3_cli = s3.connect("https://s3.frostfs.devenv:8080", {'no_verify_ssl': 'true', 'timeout': '60s', 'aws_profile': 'metal'})
 ```
 
 * `no_verify_ss` - Bool. If `true` - skip verifying the s3 certificate chain and host name (useful if s3 uses self-signed certificates)
 * `timeout` - Duration. Set timeout for requests (in http client). If omitted or zero - timeout is infinite.
+* `aws_profile` - String. Use custom profile credentials from `$HOME/.aws/credentials` file. If omitted or empty - use default profile.
 
 ### Methods
 - `createBucket(bucket, params)`. Returns dictionary with `success` boolean flag
