Accidentally pasted my Sync code into the search bar, am I at risk?

Description of the issue:
Accidentally pasted my browser sync chain code in the address bar, resulting in
search actions for engine duckduckgo. Am I at risk of anyone being able to obtain the sync code? (I cleared my clipboard)

Brave Version(See the About Brave page in the main menu):
Version 1.34.80 Chromium: 97.0.4692.71 (Official Build) (64-bit)

Type of devices currently running on the Sync chain in question:
Ubuntu 20.04

I’m very sorry I will try to get this resolved as soon as possible
