The interaction between Bonus Action spells and Action spells

Tabaxi Rogue With Second Story Work

Can unarmed strikes with tavern brawler count for 2 weapon fighting?

Martial arts affects Tabaxi, in an older tweet you said it doesnt affect natural weapons…

A level 1 monk, does it get two attacks (each hand or leg) and then a bonus attack from martial arts?

So how/what is seen by True Sight?
