First import maven dependency to UDWL
<dependency>

import generateSecureAWSHeaders from dw::com::ambassadorpatryk::aws::Auth
---
generateSecureAWSHeaders(
'POST',
'us-east-1',
'ssm',
'AmazonSSM.GetParameter',
'/',
'',
payload,
Mule::p('secure::aws.accessKey'),
Mule::p('secure::aws.secretKey'))
At second line we import Filter.dwl from dw/com/ambassadorpatryk/utils folder. Instead of slash character you need to use two colons. In order to use function from emptiness_filter you need to refer to specific function/variable like in the fifth line.
