Windows partition disappeared using Boot Camp on Mojave

I have a 2017 MacBook Pro with 250GB SSD. I created a Windows partition some time ago but stopped using Windows, so I wanted to remove it and restore the 40GB allocated to the partition back to my main partition.

According to the Boot Camp instructions, I am supposed to be able to restore the space back to my mac, but it seems that I did something wrong, since now the Windows partition has disappeared but the space is not back on my main partition.

Here is the output for the "diskutil list" and "diskutil cs list" commands:

No CoreStorage logical volume groups found

Is there a way for me to get these 40GB back?

Wow, thank you! This command completely resolved the issue in less than 30 seconds. The SSD is now back at full capacity.
