Dear Vikas,
It seems that there are some issues by using the feature in Yammer and I can reproduce the issue like yours in our environment.
I'm afraid that it needs to involve our related team to be fixed directly.
I suggest you contact the administrator in your organization if you don't have the corresponding permissions and let him follow the steps in Get support - Microsoft 365 admin | Microsoft Learn to open a support ticket to our related team as soon as possible so that they can help you fix the feature issue from their side directly.
The administrator is always the first person who subscribes the Microsoft 365 business subscription or the IT administrator in your organization.

Sorry for that our category may have limited resources on fixing the feature related issues at our side.
Thanks for your understanding and hope that the issue can be soon fixed by our related team.
Sincerely
Cliff | Microsoft Community Moderator
