Gradio chatbot image/media are too big but MultimodalTextbox buttons are too small

[bigmw]

• [x ] I have searched to see if a similar issue already exists.

Reproduction
I have been working on a multimodal chatbot as described in Gradio Demo: chatbot_multimodal

Is your feature request related to a problem? Please describe.
Problem 1: Gradio chatbot image/media display size is huge. This is not needed, but look cumbersome and leave little room to display text.
As seen in the example, the image and audio displayed in the chatbot bubbles are way bigger than needed. They don’t need to be shown in full size most of the time. You don’t really get much space left for questions and answers in the chatting area. They can be shrunk into a media type logo most of the time, as seen in most other chat apps. They should be clickable, to show the full view (images, currently appear so but no effect when clicking) or play the sound (audio, this already exists). Note similar size problems have been complained by other users but there has not be a good solution.

Problem 2: MultimodalTextbox and the attachment/mic/send buttons on the bottom are small. They shall be customizable in size. But I don’t find a way to do so.

Describe the solution you'd like
We shall have options in gr.chatbot() and gr.MultimodalTextbox() functions to change/modify the size of images/media or button sizes.
