How to push a document in icloud drive documents folder to icloud after reconnecting Mac to wi-fi

I have been working on a document on my Macbook Air 2018 while wi-fi is off. Previously, when wi-fi was on, I chose to have all my documents in my document folder to be on icloud. The trouble I'm experiencing is, when I reconnect my Macbook Air to wi-fi, the changed document (changed while offline) is not being propagated to icloud. When I look at the document on my iPhone, for example, the document is not the changed version saved on my Macbook Air. How do I push the changed document to my icloud drive?
