Vectorize/Outline Border

[michaelsboost 10]

In the app Gravit Designer if you create path with a border with a width of like 8px you can right click that layer and select "vectorize border" and it creates a "Filled" color of that vectored path rather than a border. 

My question is how can I achieve that with Affinity Designer? 

EDIT: lmao nvm I figured it out. Layer/Expand Stroke (Leaving this up incase someone else has the same problem and can find the solution right away)
