Description
Hi,
I am not able to get information about the dataset that is stored on s3 storage:
zarrUrl = 'https://s3.embl.de/i2k-2020/platy-raw.ome.zarr';
info = zarrinfo(zarrUrl);
I can access the dataset using MoBIE Fiji Viewer, but not Matlab.

Research direction
Start with the zarrinfo entry point and reproduce the exact https://s3.embl.de/i2k-2020/platy-raw.ome.zarr call in a MATLAB release older than R2024b. Compare the behavior with access through MoBIE Fiji Viewer; done means zarrinfo can retrieve information for this remote dataset in the affected releases.
