[BUG] Call Notification is showing up when teams is opened in browser

Call notifications are missing when initiating a call with cloud communications api

I have a bot configured with the required permissions to make a call to users using cloud communications api. I have initiated a call using postman. We have two users whom we want to add into the call. one of them is using Teams CLIENT and other one is logged into teams in a browser.

When we initiate a call (using serviceHostedMedia), users who logged into teams client is getting notifications, but for users who logged into teams in the browser are not getting any notifications.

Environment:

1. Browser [chrome]

2. Context [Microsoft Teams, Web]

3. Version [v1.0 Cloud Communications API]

Expected behaviour
All users should get the call notifications even in the browser

Graph SDK:

• v1.0, beta

Call ID
4d1f0000-0820-4079-8d9e-126d40117453
dd1f0100-2220-438b-a5a4-07a01a47397d

Start by reproducing the call from Postman with the Cloud Communications API and serviceHostedMediaConfig, comparing Teams client and Teams in Chrome. The expected result is that every targeted user receives a call notification, including the browser user; no repository file or test entry point is identified in the issue.
