Horizontal Justification of staves

I know this is likely covered somewhere, but a search both here and on Google generally didn’t turn it up for me.

Can someone tell me how to horizontally justify a bar so that it stretches the entire width of the page, for example if it’s a flow with one bar only?

Thanks,

Ah, note spacing! I knew it would be in layout somewhere, but I couldn’t for the life of me find it. Thanks!
