"Unmerging" merged google calendar data with jq - icalendar

Question

I have ical data containing a calendar owner's events (UID contains google.com) and events imported from hebcal.com (UID contains hebcal). I'd like to use jq to to make two separate and complete ical files. ical2json converts the .ics to .json . So far I have managed to isolate the data with
cat basic.json | jq '.VCALENDAR[].VEVENT[] | select(.UID | contains("google.com"))'
How do I recreate the original structure including just the google.com or hebal.com data?
Here's sample json of the whole structure with two events, one from google, one from hebcal. So imagine producing the same structure, but with just google events.

Desired output is:

Answer 1

Use update-assignment operator |=:
jq '.VCALENDAR[0].VEVENT |= map(select(.UID | contains("google.com")))' base.json
The output:
{
"VCALENDAR": [
{
