Playing offline with Gamepass

I'm going to answer this question . NO! gamepass games cannot be played offline . Otherwise ppl would buy gamepass download 200 + games go offline n never buy gamepass again . This is copyright and licensing issue that will stay as is . The answer is
NO

No he is trying to play online but it wont let him and prompts him to buy gamepass, but he can download and play gamepass games offline

Quoted from the Game Pass Faqs. https://beta.support.xbox.com/help/subscriptions-billing/manage-subscriptions/xbox-game-pass-pc-faq

"Most games available in the Xbox Game Pass PC Games plan on your Windows 10 device support offline play but check the details of the game to make sure yours is supported. Games from the Xbox Game Pass library can be played while the PC is offline, but for
no more than 30 days before the PC must reconnect to the internet to verify an active subscription. Most games with a campaign mode will be playable offline, but games with network co-op or multiplayer features will not work while you’re offline. While playing
offline, some features, such as the ability to purchase additional items, will not be available."

Also,

I've been having issues with the Xbox beta app for PC the past week. I've noticed that the Xbox and Windows Store apps keep changing the status of my subscription, which subscription I have, and it keeps disabling Offline Permissions by itself. Have you
checked the Windows Store app to make sure Offline Permissions is enabled there on the device you use for Offline Play? This might be similar to what you're experiencing. On the Xbox app click your avatar and select feedback and submit this there too. We might
need to get MS engineers on this.

You need gamepass to play..unless it was a popup that said you can play offline

so what your saying is in order to play gamepass offline you need to connect to the internet and from there go offline with the internet still connected?
