Will anyone have an idea how to implement deep links?
Deep links Receiving invitations
When a user receives an invitation, if the user has not yet installed the
app, they can choose to install the app from their platform's app store.
Then, after the app is installed, or if the app was already installed, the
app starts and receives the URL to its content, if you sent one. The app
will also receive the invitation ID, which will match the invitation ID on
the sending side.
Generally, your app should check for incoming invitations once, at startup.
