/*
  Warnings:

  - The primary key for the `ConversationParticipant` table will be changed. If it partially fails, the table could be left without primary key constraint.
  - The required column `id` was added to the `ConversationParticipant` table with a prisma-level default value. This is not possible if the table is not empty. Please add this column as optional, then populate it before making it required.
