To set the default landing page to 'Favourites' under the apps tab in 1912. By default, the landing page is 'Home'. The below script would help in achieving the same:

Step 1: In the Storefront console, navigate to 'Manage Receiver for Web Sites'
Step 2: Click configure and browse to 'Client Interface Settings'
Step 3: Set 'Default view' to 'Applications' 
Step 4: Take a backup of the script.js file located at this path on the Storefront server: C:\Inetpub\wwwroot\Citrix\StoreWeb\custom\
Step 5: Add the below script to the script.js file:

CTXS.Extensions.onViewChange = function(view) {
if (view == "store") {
window.setTimeout(function() {
$("#myAppsFilterBtn").click();
}, 1000);
}
};

Step 6: Propagate changes to all Storefront servers
