A star (A*) pathfinding question

Hi all,
Greetings.

I am very new on Unreal, for more than one year i use to develop games in Unity. Unreal and Unity are two different mentalities.

I can easily programe a DOS A star application on Visual Studio and i can also use A star pathfinding in Unity.

However, i have no clue how to use it on Unreal. Let say the player is controlling a blue sphere (or circle if 2D) and there is a red sphere (or circle) which is fallow him all the time.

I search on Google and Youtube but i didn’ find that much.

Which actor i must use ?

I want to know how to do it on blueprint or c++.

Thank you so much for your attention.

Greetings.
