I used to think that this was not possible but I recently saw that Testim has an extension that does this.

Core aim: Add a message in the page which doesn't interfere with the DOM/CSS of the existing page.

Chrome/Chromium injects "The browser is being automated" message in the page when the browser is run from puppeteer. But as I understood, this isn't an editable message. How is testim able to do this?

Here's a screenshot showing exact message: image showing testim's custom message as chrome infobar

This is the message that is shown, when an Chrome extension attaches to a tab via the chrome.debugger API. It shows the name of the extension which is attached to the page, in your case the Testim Editor extension.

Removing the infobar

To remove that bar, you have can either enable the "Silent Debugging" option in the Chrome flags (chrome://flags) manually or use the --silent-debugger-extension-api flag when starting Chrome. There is no way to disable it programmatically from inside your extension.
