Hi there, y’all!

I’m currently making this component that should be able to be sized responsively. However, when I drag it to widen the component, the right icon is staying in the same place. 

I’d like to keep the assets on the left (^Component) anchored to that side but anchor the plus sign on the right hand side to the right side so that it responsively widens. Does anyone have any suggestions on how to do this? Thank you so much and apologies for poorly explaining that- would be happy to elaborate!
