Embedding one SharePoint site into another

Good day!  I am want to view and navigate through a SharePoint site that is embedded via Web Part within another SharePoint site.  Why am I wanting to do this?  Long story short, our team has been moved to working from home amid COVID.  The majority of my team now only has 1 monitor display.  I am working on a temporary solution that would bring the most frequently used websites and resources into 1 page, thereby reducing the number of browser tabs open and needing to be switched through.  Both SharePoint sites are internal for my company and permissions seem to be appropriately set.  The problem I am having is when I embed the source site homepage, it's top link (navigation) bar disappears and I am unable to navigate the embedded site.  I have searched for solutions and tried a number of embed codes but the issue persists.  Any thoughts?

Many thanks,
