My gems doesn’t save the conversation

I got quite a problem with gemini.

I use gems to create sort of the equivalent of project from chat gpt(tell me if i'm doing this wrong)

Anyway, regardless of this being the right thing to do or not, each time I want to talk with my gem (a custom one), it doesn't save the conversation.

I would like it to appear as a classic conversation, that is saved and i can access later, with memory of what I said. But it doesn't work like that, and the conversation disapear after a bit of time.

So, two questions :
– are there equivalent of projects in gemini, with multiple chats with saved memory ?

– is there a way to keep in memory of gem chats I had ? They seem to disappear instantly
