Hi MihirGosai-1128,
Does anyone else have the same issue?
Do you try the windows desktop?
If this issue only happens on Linux system, it recommends you try the following distros: Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Fedora 30 Workstation, RHEL 8 Workstation, CentOS 8. As I know, these distros are supported by Teams for Linux.
Moreover, for reference, the supported web client is listed in this link:
