Is your feature request related to a problem? Please describe.
Yes - see this bug report: #225

Describe the solution you'd like
Enable dynamic content for the given tab type in order to preconfigure the website to render in the tab.

Describe alternatives you've considered
Is there currently a way of solving your problem with existing cmdlets? Optionally through the use of other PowerShell Modules (for instance by using the Microsoft Graph cmdlets or the Microsoft SPO Management Shell)
Alternative is only to develop a own teams tab which then needs to go through the process of compliance and publishing to the organization using teams admin center. A lot of work for something deadly needed.
