Handling SAML token expiry in Sharepoint 2013 using JSOM

In my custom page, I have controls where I have to do certain validation and populate controls based on some selection using client side javascript object model in sharepoint 2013

My js code looks like this

 var oLoader = SP.UI.ModalDialog.showWaitScreenWithNoClose(SP.Res.dialogLoading15);
            var clientContext = new SP.ClientContext(enteredUrl);
            var website = clientContext.get_web();

            clientContext.load(website);
            clientContext.executeQueryAsync(function () {
                // do nothing as the URL is valid
                oLoader.close();
              
                return true;
            }, function (sender, args) {
                oLoader.close();

                var msg = "Error occured";
                ShowModalPopUp(msg, "", "Popup Title");
                return false;
            });

This code works fine if the SAML token is valid. But if I keep the page open for sometime, it starts throwing popup with "Error occured".

On troubleshooting the ULS logs, we found "SAML token is found in local cache but is expired. Returning null"

I have executed Get-SPSecurityTokenServiceConfig  and found that the token is expiring after 10 mins. Now we can increase the time for expiration of SAML token, but there are some security concerns in doing so.

I was wondering if there is a better way to handle from JSOM to revalidate the token and complete the operation in sharepoint 2013.

Note: If I refresh the page and do the intended operation on the page then I don't get this error as the token is getting revalidated. 

Just to add to my finding in terms of getting saml token expiration period

The following table describes the two configuration options that directly affect when SharePoint requires a user to get a new SAML token from the issuer.
