Each app (such as a mobile browser) and device may have different methods for sharing (display sharing icon).  Even different browsers and browser versions have different menus that you would use to share.

If you see the Share icon  click it, and then look for the Zholink icon .

Otherwise, if you are using an Android device, click the button that will bring up a menu for that app.  Some apps may have a 3-dot menu button , click it and then select the Share menu item.  Some browsers may have a button next to the address bar (such as "More"), which will open up the menu.

If you are using an iOS device (iPhone), the method to share is the Share Drop.  Click the share-drop icon  and it will show a list of app icons to share with.  If you don't see the Zholink icon, then click the More button and enable Zholink, and then click Zholink in the share-drop menu.
