It always starts with:

https://fractal-scluster-staging.mls.uzh.ch/vizarr/?source=https://fractal-scluster-staging.mls.uzh.ch/data/files/shares/prbvc.biovision.uzh/fractal/bvc/users/joluet/fractal/176_kispi_benchmarks/356_10x_dataset_reruns/10x.zarr/C/3/0&viewState={"target":[1449.182990601302,899.761627013631],"zoom":-0.10827104432012573}

https://fractal-scluster-staging.mls.uzh.ch/vizarr/?source=

Then this URL pointing to your project share (project share names can vary):

https://fractal-scluster-staging.mls.uzh.ch/data/files/shares/prbvc.biovision.uzh/fractal/bvc/

Then the location of your image: e.g. users/joluet/fractal/176_kispi_benchmarks/356_10x_dataset_reruns/10x.zarr/C/3/0
