It does require registration to do much with it but…
I found that if you create your design on the initial page and then click the edit in Cuttle button, then you can select-all, copy the design and paste it into Inkscape.
Once in Inkscape I ungrouped and selected the snowflake outline and convert to path(vector). Saving the design as SVG(Inkscape std file format) will allow LightBurn or other apps to import the design having 2 layers. The black layer for cutting the outline/hole and the blue layer to engrave the text.
