You can pass your own options to opts, the default opts following:

M.config = {
    ---To handle matched treesitter node
	handler = {
		---@type table<string,string[]|string>
        ---The key is treesitter node type, value is how to treat this node. 
        ---For generic_command, value is virt_text for conceal, see nvim_buf_set_extmark
		generic_command = {},
        ---For begin, value is function(buffer,node) to do some counter-related things. 
		begin = {
			enumerate = function(buffer, node)
				counter.item_depth_change(buffer, true, 1)
			end,
			itemize = function(buffer, node)
				counter.item_depth_change(buffer, false, 1)
			end,
		},
        ---For end, value is function(buffer,node) to do some counter-related things. 
		["end"] = {
			enumerate = function(buffer, node)
				counter.item_depth_change(buffer, true, -1)
			end,
			itemize = function(buffer, node)
				counter.item_depth_change(buffer, false, -1)
			end,
		},
	},
