Can't access bot inside shared channel

I've built an application for the Microsoft Teams app and published it in my organization using the Developer portal.
I want to access the bot inside a team's shared channel but cannot do so. I've also provided "sharedChannels" inside the supportedChannelTypes property in the manifest but still, it isn't working.

The manifest of my application looks somewhat like this:
