What to use in place of deprecated api? #232

I was previously using the following commands in some custom keybindings:

in normal mode, to toggle the current line:

    "<cmd>lua require('Comment.api').toggle_current_linewise()<CR>",

in visual mode. to toggle the current block:

    ":lua require('Comment.api').toggle_linewise_op(vim.fn.visualmode())<CR>",

After upgrading recently, I'm getting an error ... deprecate ..., obviously signalling the api I was using has since been deprecated.

What should I use instead please?
