There is no Discord option o Groups and Chat (and my account is already linked)

Hi, my name is Marvina and I will be happy to help you.

I'm sorry you have this problem. Follow the instructions below for a solution.

Aspects that you should take into account:
You cannot mix Discord friends with Xbox friends. A Discord voice channel will contain your Discord friends, while an Xbox group chat will contain your Xbox friends.

Discord voice channel audio cannot be transmitted via Twitch streaming.
Discord is not available in all countries or regions.
Initial tasks

To add Discord to your Xbox, you'll first need to link your Xbox and Discord accounts in one of the following ways.
Note You will only be asked to link the first time, unless you unlink your Discord and Xbox accounts. If you previously linked your Xbox and Discord accounts before August 2022, you may need to link your accounts again to access this feature.

For more information on linking to social media accounts, go to:

Link your social media accounts to Xbox
Select your avatar > Connections.
Select Add and under Add new connection, select Xbox.
Select Continue, then follow the instructions to sign in to your Microsoft account.
Select Authorize to connect your Xbox and Discord accounts. When you're done, your accounts will be linked.

I hope I can help you solve it.

Hi, thanks for your suggestions. Yes, I've done all of those things. To be more specific, what I think I'm needing, and currently missing, is the Discord option in the friends/party chat menu.

I have created his Discord account and, using the Discord website, linked it with his Xbox account but it's not showing on the Xbox itself.

Thanks again

As already mentioned it is kinda hard to figure out what you are wanting, are you after a discord app for Xbox One that has all the features that discord on PC has?

A simple voice chat app?

A simple group text app?

Or all of the above?

Hello again,

There is not an option to uninstall discord from the Xbox Series X. Discord does not show up as an app, as it is integrated directly into the party chat functionality. Are you suggesting that I unlink the discord account?

Thanks

Hi Mark.

I'm an Independent Advisor and a Microsoft Xbox user like you.

I imagine that you have already tried reconnecting it on the console. In any case, it could be helpful if you could post some screenshots of the Xbox window to assist me in understanding the issue better. Typically, reconnecting it from the console should suffice.

To connect to Discord through your Xbox console:
Press the Xbox button  on your controller to open the guide.
Go to Profile & system > Settings > Account > Linked social accounts.
Under the Discord tile, select Link.
Follow the instructions to link your Discord account.
