A plugin that can search a calendar (ics/caldav) and return a list of events?

Hi. I haven’t yet found a suitable plugin. Hopefully someone knows one:)

I have an appointment calendar in ical format. I would like to be able to search the SUMMARY or DESCRIPTION parameter of events for a string (the customer’s name or WP user name) and return a list of their events which can be shown on a “your appointments” page for each user (customer).

The plugin amr-ical-events-list is in that direction, but the answer to a previous user question about filtering by keyword indicated that tags would be necessary. (https://wordpress.org/support/topic/filter-based-on-keyword)

Some plugins that create appointments within WordPress (e.g. Appointify) can achieve a similar list (because the appointment is created in WP and explicitly associated with a User), but the appointment creation process is slow and too complicated, so I prefer to access the event data from my normal external appointment calendar.
