I can't add date and time for reminder on icloud.com

Hello! often use the reminder app on my iPhone. I really like this program. But with this program on icloud.com I can't add date and time for reminder. I can only add a reminder text. After synchronization, there is such a reminder on my phone, but I have to add the date and time for it manually. Please tell me how to add the date and time of a reminder if I create it using icloud on my computer. Thanks!
