PromQL question

Hi, i have a hopefully simple PromQL question:
increase( label_replace( watchdog_api_monitor_success_distribution_count{namespace="prod"},"action","GetLatestFirmwareUpdate","endpoint","(.*)")[60m])
throws: invalid parameter ‘query’: parse error at char 149: range specification must be preceded by a metric selector, but follows a *promql.Call instead

-> I did not find any example on how to use label_replace in other queries. What am I doing wrogn here? The label_replace part itself works as expected, it is returning a vector. So what is wrong with the syntax?

Thanks in advance!

I think I found it: LABEL_REPLACE is not supported by range vectors…
