Unable to Attach Images in Chat

I am currently using two devices. On my MacBook Air, there is a button to insert images in the chat, but on my Mac Mini, that option is missing. Both devices are running the same version. The screen design is also different, so I would appreciate it if you could explain why this is happening.

Hey @kozue4124

Try expanding the sidebar by dragging it with your mouse. Sometimes the image insert button might be hidden if the sidebar is collapsed. Also, you can paste images directly into the chat using the shortcut cmd+v.
