At the time of providing EPF credentials on - https://kuvera.in/portfolio/epf/add-epf, you will get an option to choose whether you want to store your EPF password on Kuvera or not. If you save your password then EPF balance will update automatically at a monthly frequency.
If you have already given EPF details and did not choose to store password then you will be able to manually request for EPF update after 15 days from previous update (refresh icon will appear on EPF page). At the time of manually updating EPF details, you will again see the option to save credentials for automatic update in future.
