Send image with caption is missing.

[maulikgoyanidbc]

I want to send caption with image. There is no method to send caption.

var echo: MXEvent?

    room?.sendImage(data: imageData,
                    size: image.size,
                    mimeType: "image/png",
                    thumbnail: nil,
                    blurhash: nil,
                    localEcho: &echo,
                    completion: { response in
        print(response as Any)
    })

This is Matrix SDK function to sendImage.

Can anybody help me on this?
