Few queries related to mito & CEL input

[getkub]

Sorry for basic questions as i'm pretty new to mito

• Can all the functions/options within this package works in filebeat CEL input? or there is a waiting period before mito library updates are ported to filebeat?
• Any simulation envrionment out there to test this? May be a suggestion to include mito into the 'dev tools' in Kibana?
• Also as per post: https://discuss.elastic.co/t/cel-input-how-to-subtract-1hour-from-now/351894 , how can we subtract /add time to now() ? Say for example I want to find events from past 5 minutes how can we put is there a way to put now()-5m kind of option anywhere?

thanks @efd6 Dan for creating this powerful tool/library with filebeat
