How can I set the Calendar to have Monday instead of Sunday, as the first day of the week?

I have a list of images to display thumbnails. On top of that, for each image, I want to click it to show the image on the full size.

I am Nextui with Next.js I want to prevent the Popover from closing when interacting outside of it. I have used the shouldCloseOnInteractOutside prop as per the documentation but it’s not able to prevent the Popover(NextUI) from closing when interacting outside of popover. Setting the prop isKeyboardDismissDisabled to true is making sure that I can’t use the esc key to close the popover, however when I click outside the popover, it’s closing.
