Hello, in evey task we have a "limit date" field (date_deadline)

but we need that field to include the hour the task should be delivered (i.e 03/07/2023 15:00 Hours). We can easily add that new field using Studio, but the problem is that the new field is not visible by portal users in their portal. (we already made it visible to them in groups, but is still not visible. Portal users can only see the original field (Limit date), which is not useful to us because we deliver multiple tasks a day, could you please help us with this?
