I tried a Text Blaze snippet on the website copilot.microsoft.com in the Edge browser and it doesn't seem to work. Is there a way to fix it?
Hi @nektorom Welcome to the forum! 
You are right. It looks like the Edge browser has restricted the site https://copilot.microsoft.com/ from all browser extensions - not just ours.
You can use the Text Blaze desktop apps to workaround this.
It works okay if you use the Assistant
