Hi Shubham,
Thank you for connecting with us on Microsoft community.
According to your description, seems like your teams-js library concern environment is associated with Developer platform or SDK or Java script programing platform, I was consulting your thread with my team members, I would like to share some more specific direction information with you, actually Microsoft has separate community channel resources where our related most valuable professional and community members can provide possible information for certain different support scope resources platform, so would you mind to contacting and placing your concern on our dedicated separate Microsoft Teams Development - Microsoft Q&Acommunity channel?
Actually, this community does not focus Developer platform or Java script / SDK or any programing script related scenario for Microsoft Teams. But this community is mainly focusing Microsoft 365 Business license subscription services related scenario for Teams application.
However, there is an another specific channel for your mentioned concern where you may get some possible information for certain specific resources and platform from our related community members.
I would greatly appreciate your valuable cooperation and valuable time.
Sincerely,
Vaidya Darpan
