Zoom phone icon is available for Sales,Service not available for custom lightning apps.

[Shikher]

Hi Zoom Community user,
I have installed zoom for lightning in my salesforce ecosystem. After trying and configuring zoom phone i found that Zoom phone icon is not visible in Custom Lightning App from Applauncher but its visible and working for Sales, Service console apps.
Could anyone please let me know if there is any config i need to set to make it visible for all the custom lightning apps.

One more issue i am facing with it is that for some users Icon label is showing as "Phone" but for some users its label is showing as different one like "RingCentral" which is another call center. How do i rename that.

Please help me , stucked here.
