License agreement custom visuals

Hi,

I am embedding power bi into our web application and would like to use some of the custom visuals from the office store. This web app will be for my customers to consume at cost. Is there anything I need to be aware of using the custom visuals from the office store? It is my understanding that once it's in the office store it is free for use and can be used in the manner in which I am trying to use it. Thank you in advance for your help in me searching for this answer.
