Checkout UI Extension CLI - won't show client stores

[GilSeeed]

Hello Shopify team, I'm trying to generate an APP/Extension for Checkout, I've been using the CLI perfectly in the whole development, but now I need to start testing on Clients store, but on the CLI doesn't show any store that I have access as a collaborator, there's a way to select another store outside my partner store list?

Basically, it's only showing one store (from my partner), I expected to get a list of my stores + client stores (obviously I've been invited and accepted)

Same problem here.
At the moment only solution I found is to deploy it, install it on my customer store and test it on a checkout profile.
Downside of this behavior is that you have to deploy each and every time you do modify your extension.

Exactly, I'm doing the exact same "solution",

A very poor experience solution unfortunately. 
Hope they fix this, or to find out if I'm missing some permissions to do that.
