Remove or Change IG account linked to this 'block'

#1

Hi everyone–end blog user here. I’m working with a client whose developer connected Ghost as our blogging platform. So far so good aside from this IG image block that is set up to link to “aspire theme”. I’d love to know how to change it to our IG handle…is this something that needs to happen on the backend, or am I missing a way to edit this feature while in the blogging space?
