I am trying to change the name “Knowledge Base” to “Help Center” in our Portal. 
 

From what I’ve read, it looks like the only way to do this is by customizing the code under Admin > Channels > Portals > Customize > Edit theme. 

We are trying to not spend development resources on this, but I’m having trouble finding a good way to make this change in the code editor.

Does anyone have an existing script that we can use to make this change?
