Alongside photos and voice notes, you can share documents like PDFs or spreadsheets directly in a chat.
Open the chat you want to send the file in.
Tap the + button on the message input bar.
Select File from the attachment options that slide up.
Choose the file from your device.
Optionally add a caption, then tap Send.
The file appears in the chat as an attachment that participants can tap to open or download.
Note: Very large files may take a moment to upload. If sending fails, check your connection and try again.
