What is the ruling on creating a WhatsApp group for daily supplication for the deceased relatives of each member in it?

Supplicating for the deceased is a prescribed act, and reminding their family of it is permissible. Therefore, creating a WhatsApp group to remind subscribers to supplicate for the deceased is permissible. However, if the purpose of creating the group is for daily and continuous gatherings to supplicate for the deceased, this resembles gathering for supplication in a manner that becomes a regular custom, which is prohibited.
