List name of active users - Bonita 7.5

Hi all,

at bonitasoft 7.5.4. we would like to list the names of active users of a process.
How can i reproduce this in a groovy script.
In older version, i have an example:

apiAccessor.getQueryRuntimeAPI().getActiveUsersOfProcessInstance(new ProcessInstanceUUID(my_uuid));

Thank you in advance.
