Search and delete in google calendar

I need to search my google calendar before adding new events to it, in order to avoid duplicate entries.

Questions: How can I search my calendar for e.g. the following year for events containing specific phrases from automations/node red?
And how can I delete an event from automation/Node Red?

Have you found a solution for this. I have the same problem and cant find answers anywhere…

Sorry, no. Still hoping for a solution, as it’s difficult to use for my purposes the way it is now.
