send_file
Send end-to-end encrypted files to LINE conversations. Accepts any file type for 1:1, group, or room chats using file path or base64.
Instructions
Sends an E2EE file attachment (any type — .docx, .pdf, .zip, …) to a LINE conversation immediately (same pipeline as send_image; the original filename is sealed end-to-end). Works for 1:1/group/room; fails honestly if the key cannot be resolved or the upload is rejected. One send per call. Provide exactly one of filePath or fileBase64; fileName is required with fileBase64 (and overrides the basename when given with filePath).
