Currently as per Salesforce document we can access the email body using "messageBody" attribute. Salesforce link : https://developer.salesforce.com/docs/atlas.en-us.lightning.meta/lightning/components_config_for_app_builder_email_app_pane.htm
But how can we access the attachment related to email? Salesforce do not give any function or parameters to access the attachment anywhere in document. If someone worked on it then please help me on this.
Basically I need to replicate the "standard relate email" functionality from Lightning for Outlook and perform some customization on it.
