AWS DocumentDB change stream data availability from default to 24 hours

Started to use AWS DocumentDb change stream, want to keep Events written to a change stream for a database for 24 hours instead of default 3 hours. How I can do this. Standard AWS docs provide just this:

db.adminCommand({modifyChangeStreams: 1,
    database: "",
    collection: "", 
    enable: true   
    });

ekaterina@, you are correct, the docs for change streams are not clear and we will fix that. You can change the default retention period change_stream_log_retention_duration to 24 hours. Here are the docs on how to change cluster parameters, in general: https://docs.aws.amazon.com/documentdb/latest/developerguide/cluster_parameter_groups-parameters.html

There is 'Parameter groups' on AWS Document Db console. Choose your cluster group if created, if not use default. There are several cluster parameters available, one of them: change_stream_log_retention_duration, max value can be 86400 which is 24 hours in seconds. Haven't had permissions to see that. Hope it will help someone else.
