Create a link on Canvas details page to open a Zoho Forms form

Create a link on Canvas details page to open a Zoho Forms form

We have many forms for client onboarding and offboarding. Our sales and client coaches barely know how to use Zoho CRM, so I've created Canvas views for most of the modules they use. It's made it easier but now we need to add the ability for them to access forms from Zoho Forms.

The easiest and most direct way to do this is to add a link or button to the Canvas page that, when clicked, opens the form in a new browser tab. I've tried to do this by adding a button element and writing a very simple one-line JavaScript onClick function.  It doesn't respond. There are no errors. It just doesn't do anything.

The button has an ID. I added the script by right clicking the button and selecting "Add Client Script". Then I added:
  1. window.open("https://zfrmz.com/33ZjnGk4n8hnh4qLh7At", '_blank');
It's just a simple line to open the form. It works just fine in the real world but not in CRM.

How do I do this? How do I provide links to forms on the Canvas page?
