Begin by selecting the cabinet that you want to change the handle for.

Look for the menu labeled "Shutter" or "Drawer" on the right of the design panel. It would be arranged in a vertical order for example, as Cabinet>Partition>Shutter System>Shutter> Panel etc. Click on it to access the settings related to shutter.

Within the "Shutter" menu, you will find the "Handle" option. This option may be available under both the "Quick Access" section and the "Customise" section, making it convenient for you to access.

Next to the "Handle" tool you will see a red trash bin. Clicking on the same, will remove your handle from the selected shutter.
