Ugly Defender awareness training screen

I want to use the extensive training material available from the E5 licenses we just shelled out a boat load of $$ for.

However, when someone gets an invite and they click the link to do the training they are taken to the Defender page.  This might be fine for a technical person but its ugly as F for my users.  Plus, there is extra rubbish like Threat Intelligence, Trials, Reports, settings etc they can access that I don't want them too.

This is not a very polished interface for non-technical people.  Is there a way to fix this?

Can it send them the direct training URL, so it just opens the training and not the defender page from them to open the video?

Can we do a custom landing page but put the assigned training URLs into that?

This is ugly there has to be a way to make this more user friendly.
