Elastic ungrouped data request: Are scroll parameter and from parameter compatible

Hi All,
could you please help me with scroll api:
I need to execute raw request to elastic, with offset. I send following
request:
{
"from" : 20,
"size" : 2,
"query" : {
"match_all" : { }
}
}
It works correctly,2 first records are skipped. But if I add parameter
"scroll" to query,e.g."scroll=5m", to start scrolling, "from" parameter is
ignored.
Could you tell me please if it is know issue or actually expected behavior?

Thanks,
Iana
