Need help publishing my nicepage site through nicepage

I used nicepage site builder to create my site, which is ready to publish. I was going to upload it to ionos but decided to publish with my NP webhosting. re-directing the dns is getting incredibly confusing. I NEED SOMEONE TO WALK ME THROUGH THE SETTING ADJUSTMENTS SO i CAN JUST GET THIS SITE PUBLISHED THROUGH NP. this is getting way more complicated than it needs to be.

To explain the switch in hosts, I started with ionos but found np site builder much superior. after building the site decided to publish through np.
