No Lightroom Catalog created

No Lightroom Catalog created

Hi there, when I convert an Aperture library to Lightroom with Avalanche 1.3.9c (running on Mac Mini M1 / Big Sur 11.4) all the files are copied to new location, but no Lightroom Catalog seems to be created - there's no option on the final screen (screenshot attached) to open the catalog, and I can't find one anywhere ...

Any ideas ? thanks in advance ...
