Shortcut to expand or collapse the Vertical Tabs sidebar?

Hi everyone, is there a keyboard shortcut in Brave to expand and collapse the Vertical Tabs sidebar, basically toggle it between expanded (show tab titles) and collapsed (icon-only)?

Firefox has a shortcut for this, and Arc and Zen Browser also offer a similar toggle. I am looking for something equivalent in Brave, either built-in or via a flag, setting, or extension.

If there is no shortcut today, is this something already requested or on the roadmap?
