Is inspiring smite a bonus action in 2024?

Hey everyone!

I've been trying to migrate my character to 2024 rules but theres a slight inconsistency in the rules. In DNDBeyond app inspiring smite is listed as a bonus action and so is divine smite. Does it mean that inspiring smite is completely unusable since you need to do an attack (action), divine smite (bonus action) and inspiring smite (bonus action)? Is it just a bug in the app or am I supposed to magically conjure 2nd bonus action?
