Custom Hotspot Login Page

I am using the MikroTik Cloud Core Router CCR-1016-12S-1s+RM. My goal is to use the MikroTik Hotspot feature to provide free public wifi. The conditions of the access will be once the user is connected to the wifi and opens an internet browser, a video is displayed on the login page (like an advertisement where you could not exit out), once the video is over a button will appear for a one click login that leads the user to the internet (i.e. Google).

Does anyone have any experience making this successful have tips and sample code they could share? I have the YouTube video embed code and the one click login code but I am need helping making it all work in the sequence I need.

Please Help!
