If you would like to minimize the Lusha window to an icon, toggle the "Auto-open plugin" option.
By doing so, the results window will not open automatically each time you visit a profile page.
Instead, only the Lusha icon will appear.
If contact details are found for a specific profile, a number will appear on the Lusha icon, indicating the number of contacts found.
Click on the icon to open the window.
One more thing!
You can move the Lusha icon up and down simply by dragging the 6 dots button under the plugin with your mouse.
