Remove Ad for Copilot Pro from Word iPad toolbar

Recently this icon appeared on my toolbar in Word 365 on iPad. It’s an ad for purchasing Copilot Pro, and it is in the first position on the top-right toolbar. Not only that but it obscures the center toolbar, and I can find no setting or method to get rid of it.

The toolbar is not the place for ads on a paid product--especially not ones that cover up the actual software functions--and I have no interest in Copilot Pro. There needs to be a setting to remove this ad.
