Rogue Assassin / Arcane Archer Multiclass?

I’m fairly new to this game. I’m currently runningy second playthrough with deep gnome rogue assassin.

I was looking at potentially multiclassing for the first time, and thought Arcane Archer might make sense to gain second wind, extra attack, specialty arrow?

Anybody better than me want to help me think about what an optimal/good enough setup would be or whether this even makes sense to look into?
