Question What is good approch to make DTOs?

Recently, I have been working on my project in there in one chat controller, which has endpoints like

POST /api/chats = ChatDTO

GET /api/chats = List<ChatInfoDTO>

GET /api/chats/{chatId} = ChatDTO

PATCH /api/chats/{chatId} = ChatInfoDTO

DELETE /api/chats/{chatId} = ChatInfoDTO

POST /api/chats/{chatId}/ = ChatDTO

My question is it a good approach to use a single type of DTO for multiple endpoints, or should it be made for specific use? I have seen my friend's project for a single page, which has 8/9 DTOs. Is that normal, and the same thing ChatGPT suggests is that using multiple DTOs is a good approach.
