Prevent session timeout without changing global setting

[Fjonan]

We created a seating plan editor in Nova which means a logged in user can spend a lot of time creating it (we integrated FabricJS so the users can use a canvas to create the plan) locally without actually sending anything to the server and when it's time to save the session has expired.

Now, I am looking for a clean way to prevent this without having to globally extend the session time to unsecure lengths. I was thinking of a kind of keep alive that is send from the edit view to the server when the user is interacting in some way without really saving anything.

I did not find anything in that regard so I am asking: is there an official/clean way to send keep alive requests from Vue to the server so the user - in this specific case - does not get logged out while creating the complex seating plan client side?

Thanks.
