I am using Elementor and the projects of my theme, so it was a bit tricky.
But it worked for me, many thanks!
For everyone with the same problem:
First use the VP Portfolio/Projects tab and insert the more block as shown in the screenshot above.
Then klick on the settings in the upper right corner and switch to the Code-Editor. Copy the code from the more block and paste it throw a html-widget in elementor. Done!
