Coming soon pro plugin

Dear forum member,

I’m currently working on my website, so I’ve used a coming soon pro plugin to inform people that the website is in progress. Now I’m asking myself if there’s a way to upload a register page made in html without the wordpress theme, so that people can be linked from the coming soon page to a register page. I tried it but after I entered https://www.mywebsite.com/register it still leads to the coming soon page. Is there a way to solve this?

Many thanks!
