Reserving App Name

Create the app in App Store Connect. You don't have to fill in any details other than the name and SKU, I think.

Thanks allot, SKU means ?

Just go to App Store Connect and start to add a new app you'll see what it means. It's just a product code that means something to you. It means Stock Keeping Unit.

Like a clothes manufacturer has a SKU for the red t-shirt in Medium might be REDM, they'll have a SKU for the red t-shirt in Large which might be REDL.

Oh I see, thanks allot, and this can be done in the Connect App or just tgrough web page ? — Kind Regards

I don't think you can add apps in the Connect app. Just go to the website.
