- export as SVG (File > Export Diagram As > SVG... > Save)
- open SVG file in web browser
- open console and run
document.querySelectorAll("text").forEach(e => e.innerHTML = e.innerHTML === "UNREGISTERED"? "":e.innerHTML)
- take screenshot
Just open the SVG file in a text editor and replace the UNREGISTERED text with empty
is there any to achieve that if I'm using ubuntu? if so, please let me know how to
