---@function Helper function to add keymaps with common properties
---@param lhs string|table The keybind (or list of keybinds)
--- This field can be the following:
--- - A string representing the keybind
--- - A list of strings representing a set of keybinds
--- - A table of multiple keybind specifications
--- This field is required.
---@param rhs string|function|nil The function to execute when the key is pressed
--- This field can be the following:
--- - A string representing the vimscript command
--- - A lua function (only when using which-key.nvim or global keymaps)
--- This field is required.
---@param desc string|nil The description of the keybind (optional)
--- This field can be the following:
--- - A string representing the description
---   The description will be displayed in the which-key menu
---@param mode string|table|nil The mode(s) in which the keybind should be added (optional)
--- This field can be the following:
--- - A string representing the mode
--- - A table of multiple modes (only when using which-key.nvim or global keymaps)
---@param icon string|nil The icon to use for the keybind (optional)
--- This field can be the following:
--- - A string representing the icon (only when defining a menu)
---@param group string|nil The group to add the keybind to (optional)
--- This field can be the following:
--- - A string representing the group (only when defining a menu)
---@param bufnr number|nil The buffer number to add the keymap to (optional)
--- This field can be the following:
--- - A number representing the buffer
---   This option is incompatible with some extended keymap options
---@param hidden boolean|nil Whether the keybind should be hidden (optional)
--- This field can be the following:

---   This option is only compatible with which-key configurations
---   It will be ignored if which-key is not installed
---   The default value is false
---@return boolean condition true if the keybind was added, false otherwise
--- There are three main types of keymaps:
--- - Global keymaps
---   This is the most common type of keymap.
---   Ex:
---     add_keymap("<leader>ff", "lua require('telescope.builtin').find_files()")
--- - Buffer keymaps
---   This is used to add keymaps to specific buffers.
---   Ex:
---     add_keymap("<leader>ff", "lua require('telescope.builtin').find_files()", nil, nil, nil, 0)
--- - Which-key menus
---   This is used to add which-key menus.
---   Ex:
---     add_keymap("<leader>l", nil, nil, nil, "󰒲", "Lazy")
