Thanks, got it to work. Snippet I'm using:
def getPathFromAsset(asset):
repository = maxon.AssetInterface.GetUserPrefsRepository()
assetId = maxon.Id(asset)
assetDescription = repository.FindLatestAsset(maxon.AssetTypes.File(), assetId, maxon.Id(), maxon.ASSET_FIND_MODE.LATEST)
return assetDescription.GetUrl()
print(getPathFromAsset("file_e55289b63600ab3c"))
