How to range format with nvim 0.9.0?

Question

I don't set a mapping to format code because it is not something I do all the time. So previously, I used to have a command to format or range format as follows:

" format code
command! -range Format if <range> | exec 'lua vim.lsp.buf.range_formatting({ timeout_ms = 2000 })' | else | exec 'lua vim.lsp.buf.format({ timeout_ms = 2000 })' | endif

But Nvim now gives me this message:

vim.lsp.buf.range_formatting is deprecated, use vim.lsp.formatexpr or vim.lsp.buf.format > instead. See :h deprecated
This function will be removed in Nvim version 0.9.0
stack traceback:
        /usr/share/nvim/runtime/lua/vim/lsp/buf.lua:407: in function 'range_formatting'
        [string ":lua"]:1: in main chunk

How can I set a command (not a key mapping) to format the selected text, when there is any, or the entire buffer if not?

I would do:

command! -range Format if <range> | exec 'lua vim.lsp.buf.format({timeout_ms = 2000, range={["start"]={row=<line1>,col=0},["end"]={row=<line2>,col=0}}})' | else | exec 'lua vim.lsp.buf.format({ timeout_ms = 2000 })' | endif
