How to launch Microsoft teams calendar Event

Hello Everyone,
I really need help in below issue.
I am creating a meeting app where I am trying to create/edit a Teams meeting from Canvas app. I want to keep the UI exact like Microsoft Teams

but due to some issue I was not able to make an exact copy of if in my canvas so I have created a button and on click of the button I am navigating to above screen.
I have a +Create Meeting button
Onselect :Launch("https://teams.microsoft.com/l/meeting/new?subject=")
so I can easily navigate to teams meeting

Problem:
I want to update the meeting in Microsoft Teams.
I have a gallery which shows all the upcomming events from my outlook

now If I click on pen Icon I should navigate to that particular event in Microsoft teams to edit the meeting.

I tried launch fuction but could not able to get the particular event details in it.
If anyone knows how to do it please let me know.
Thanks in advance.
