Get All Attachments from a message view

[Kavya HL]

Hi team,

We have a Chrome extension https://chrome.google.com/webstore/detail/fyle-expense-management/abggpefphmldapcoknbcaadbpdjjmjgk which is used to submit business expenses.
We were able to get the file attachments from the emails earlier using the getDownloadURL() method since it's deprecated we can no longer get the attachments without user interaction. 
We figure out a way to do this using the _attachmentCardImplementation._element of AttachmentCardClickEvent options. 
Can you please confirm if this is okay to use the _element options to get the download URLs?
Also is there any chance getDownloadURL() will be back in the later updates?

Thanks,
Kavya H L
