Tiles layer link to azure blob storage

Question

Hello, I would like to have authenticated access to a static X/Y/Zoom tile layer I store on an Azure storage.
The tileURL should look something like following:

https://storageaccountName.blob.core.windows.net/containerName{z}/{x}/{y}.png'

I test the url with static value and it works but layers does not appear in the maps . The goal is to host the map in a web app or powerbi Do you know if its possible to link to storage or there is an other solution to do so? Thanks for your help.

It's possible to link to tiles in blob storage, I do this a lot. The key thing is you need to enable CORs. Here's how to do this:

1. Go to the blob storage account resource in the Azure portal that will be hosting your files. For your URL format, make sure you have the correct folder structure folder Z -> folder Y -> file name X.png. Alternatively, give your files quadkey names and then you can just drop them into a single folder.
2. Under Settings, click on the Resource Sharing (CORs) button.
3. Under the Blob services section, add new entry with the following options:

Allowed origins	Allowed methods	Allowed headers	Exposed headers	Max age
*	GET	*	*	360000
