QUESTION: Adding weekday and weekend seasonality for a 15 minute frequency dataset

I have a question regarding adding custom seasonalities using Prophet in python.

My dataset has a measurement frequency of 15 minutes and I would like to handle weekdays and weekends differently. The docs says that daily seasonality is automatically fit when we have sub-daily data. Is it enough to turn it off by setting `daily_seasonality=False` or will it still fit a daily seasonality.

In terms of adding a custom seasonality, if my input data has a freq of 15 minutes, is the period for weekday and weekend seasonality be `96`?
