How do I insert a copyright symbol in Canva?

As a designer seeking to ensure the integrity of my work, I often need to include a copyright symbol within my designs. Can you walk me through the process of inserting a copyright symbol in Canva? I've tried searching for a direct option but haven't been able to find one. Is there a specific tool or shortcut that I should be utilizing? It's important for me to ensure that my designs are properly attributed and protected, so any guidance you can provide would be greatly appreciated.
