Trigger the extension with a floating button

You can modify the source code so that a floating button is used to trigger a custom script that shows the Chrome extension.

Check out the sample script customScript1.js which injects a yellow button into bubblehacks.io:

// Create a rounded floating button in the bottom right corner and inject into the DOM
let button = document.createElement("button");
button.innerHTML = "C"; // Button label
button.style.position = "fixed";
button.style.bottom = "20px";
button.style.right = "20px";
button.style.zIndex = "9999";
button.style.borderRadius = "50%"; // Makes the button round
button.style.width = "50px"; // Circle width
button.style.height = "50px"; // Circle height
button.style.lineHeight = "50px"; // Vertically align text
button.style.textAlign = "center"; // Horizontally align text
button.style.padding = "0"; // Adjust padding to 0 for alignment
button.style.backgroundColor = "yellow"; // Yellow background
button.style.color = "black"; // Black font color
button.style.border = "none";
button.style.cursor = "pointer";
button.style.boxShadow = "0 4px 8px rgba(0,0,0,0.3)"; // More prominent shadow
document.body.appendChild(button);

button.onclick = function () {
    // Send a message to background.js to open the iframe sidebar
    chrome.runtime.sendMessage({ type: "openIframeSidebar", url: url, width: width }, function (response) {
        console.log(response.status);
    });
};

This is how the yellow button will look on the page specified (in this case bubblehacks.io):

Important: Make sure the js file is injected into the appropriate page and has appropriate host permissions by adjusting the manifest.js

This only works for the sidebar or full screen modals. Not for the extension popup. If you need a popup, please adjust the sidebar CSS to make it look like a popup.
