Optional. The filter expression. For example: imagery_type=SPHERICAL. The filters supported are: imagery_type, processing_state, min_latitude, max_latitude, min_longitude, max_longitude, filename_query, min_capture_time_seconds, `max_capture_time_seconds. See https://google.aip.dev/160 for more information. Filename queries should sent as a Phrase in order to support multiple words and special characters by adding escaped quotes. Ex: filename_query="example of a phrase.mp4"

Optional. The maximum number of photo sequences to return. pageSize must be non-negative. If pageSize is zero or is not provided, the default page size of 100 is used. The number of photo sequences returned in the response may be less than pageSize if the number of matches is less than pageSize. This is currently unimplemented but is in process.

Optional. The nextPageToken value returned from a previous ListPhotoSequences request, if any.
