Hello @hosendarp,
thank you for your question. 🍀
For security reasons the access token is valid for several hours and if you don't refresh the token (by performing any action) it will eventually time out and sign you out.
But I believe if you reload the dashboard periodically (like every 2 hours for example) it should last for few days.
You might want to search for something like a browser extension, that refreshes the screen periodically, but that is an external solution, that you will have to explore yourself. But even this solution won´t last for eternity and will eventually log you out 🙂
