How to change root in the file tree?

[gelerum]

Is this a question?
I hadn't found any map to change root in the file tree, everybody needs to know it.

Additional context
After i go upper (change root to the directory above) i want to select any other directory as root of the file tree.

vim.keymap.set('n', '<C-]>', api.tree.change_root_to_node, opts('CD'))
