Change behavior of imageClickAction based on window size?

[lococola]

Love the PhotoSwipe plugin so far. So I would like to accomplish two things, depending on whether the gallery is viewed from a mobile device or not.

If browsing on a mobile device, I want the user to be able to click on the image to zoom in to max viewport.
If browsing on desktop, I want the user to not be able to zoom in at all. Instead, a click on the image should close the gallery.

I have tried several things but I can't get it to work. This is the code I have so far:

function isPhonePortrait() {
			return window.matchMedia('(max-width: 600px) and (orientation: portrait)').matches;
		}
		var lightbox = new PhotoSwipeLightbox({
			gallery: '.landscapes',
			children: 'a',
			
			initialZoomLevel: (zoomLevelObject) => {
				if (isPhonePortrait()) {
					return zoomLevelObject.fit;
				} else {
					return zoomLevelObject.vFill;
				}
			},
			secondaryZoomLevel: (zoomLevelObject) => {
				if (isPhonePortrait()) {
					return zoomLevelObject.vFill;
				} else {
					return 'fit';
				}
			},
			maxZoomLevel: 1,

This takes care of the zooming/non-zooming bit, but I don't know how to add the code to make the gallery close on a image click. I tried to add different variations of this code:

imageClickAction: (releasePoint, e) => {
				if (isPhonePortrait()) {
					return releasePoint.zoom;
				} else {
					return releasePoint.close;
				}
			},

But it doesn't work. Any ideas what I need to enter here?

imageClickAction corresponds to click on the image with mouse, for tactile devices there is tapAction - https://photoswipe.com/click-and-tap-actions/
