I want the home button in menu to link to my main site/domain

So I have a site, say abc.com (only an example) whose homepage setting is “Your homepage displays: your latest posts”

That’s fine because that’s how I want it. The problem is, I made a page called Home and added it to the menu, so it shows on the top right when abc.com is opened. However, when I click it, it takes me to abc.com/home, whereas I want it to take me to abc.com (where I already was). The page editor won’t let me put nothing in the permalink box.
This is important because there will only be one other page/menu item called “About”, so the homepage should be Home.

Another thing. If possible, how can I make the Home button in the menu colored when a visitor is on abc.com, but make it black/default when the visitor opens the About page? I have elementor if that changes anything. Thanks.
