Encoded HTML link from button field breaks the command

Currently I have a HTML prompt that will launch iMessage on Mac and prepopulate a body of the message.

The formula looks like

SMS:/ (123) 456-7891 /&body=Hi person, it was great to see you!

When I input this into my web browser, it works great: launches imessage, prepopulates the number and text body. I want to get the button field to launch this HTML line: PROBLEM is that when I launch the button “open URL” it encodes the HTML line automatically and outputs something like-

http://sms/%20(123)%20456-7891%20/&body=Hi%20,%20it%20was%20so%20good%20to%20see%20you%20last%20night!

This no longer works and just says site cannot be reached. Any help or suggestions?

Hello @newdatabasedesignguy,

Adam from Airtable here.

Our article about the button field may be helpful here. To help me understand a bit more about your setup, could you take a screenshot of your base and show all the specifics of how your button field is currently set up?

Thanks!
