Does Slashing Flourish work with Fancy Footwork?

The Fancy Footwork feature of the swashbuckler rogue says:

At 3rd level, during your turn, if you make a melee attack against a creature, that creature can’t make opportunity attacks against you for the rest of your turn.

The bardic College of Swords slashing flourish feature says:


If I use the slashing flourish attack and hit 4 other creatures around me with it, does fancy footwork affect all of them so they cannot make opportunity attacks against me?
