Pymongo mongdb delete one querying issue

Question

I am new to mongodb and I am attempting to have a query that will delete a timestamp in voice_activity when provided the id to the left of it. The date is unknown to me at the time of the query. I am doing this with Python. I have provided a Compass screenshot of what I am referring to

I attempted to find the document at first but the only query that is providing me results is search by _id.
