Text shown on the email invitation for the user to accept the invitation. but it acts a bit differently on iOS/Android:

Android: Text shown on the email invitation for the user to accept the invitation. Default install text used if not set. This must not be set if emailHtmlContent is set.

iOS: Sets the text shown on the email invitation button to install the app. Default install text used if not set. Maximum length is 32 characters.

Sets the app description displayed in email invitations. but it acts differently on iOS/Android:

Android: Sets the HTML-formatted (UTF-8 encoded, no JavaScript) content for invites sent through email. If set, this will be sent instead of the default email. This must be set along with emailSubject. and callToAction must not be set.

htmlContent must be valid HTML for standard email processing. The pattern %%APPINVITE_LINK_PLACEHOLDER%% should be embedded in your htmlContent and will be replaced with the invitation URL. This url is a link that will launch the app if already installed or take the user to the appropriate app store if not. In both cases the deep link will be available if provided using url. Must be valid (MAX_EMAIL_HTML_CONTENT bytes or less).

iOS: Sets the app description displayed in email invitations. Maximum length is 1000 characters. But it is no longer supported

Android: Sets the invite message that is sent to all invitees. Must be valid (MAX_MESSAGE_LENGTH bytes or less), including the length of translated and generated messages. The message can be edited by the sender.

iOS: Sets the default message to use for the invitation. This is the message that will be sent in the invite, for e.g., via SMS or email. This message must not exceed 100 characters. The message will be modifiable by the user. Maximum length is 100 characters.

Sets the deep link that is made available to the app when opened from the invitation. This deep link is made available both to a newly installed application and an already installed application. The deep link can be sent to Android and other platforms so should be formatted to support deep links across platforms.

Initialize a new object of type InvitesBuilder for configuring your invitation settings. When the object is configured, you should use the Invites.send method and pass inthe configured object into it so that the invite dialog would open. Note that on iOS, the user must have signed in using the Google Signin ANE before the dialog can be opened.
