New routing filter rule, "filter" command

Hi,

I’m trying to understand the new doc of routeros 7, but get stuck into commands, precisely the “filter”.
https://help.mikrotik.com/docs/pages/viewpage.action?pageId=74678285

I intent to remove all communities received as 65000:n, is what that command do?
Something like this? “filter bgp-communities ^(?!65000).*”

Or should use the “delete” command?

Any ideas?
