F5 APP Using APM

Hi D.C. Experts,

I Created A VPN using APM but I want to access that using F5 Access app from App Store. But I don't want to login every time when I am using that. When I enabled F5 access app with asking login I want to get the page. Is there any way to configure that using APM ? By checking client side certificate ? If they have it in browser then need to direct page if they don't have it then then need to go logon Page. I created policy but how do I need to enable that ? Any suggestions or ideas on this ?

Thanks in advance.
