understanding the events in the config

[ctfrancia]

i have a workflow that looks like this:

1. I enter a custom bash script that will create a file in my "work" vault location
2. when I enter that new note in neovim it will check to see who the user is and then set the workspace manually through there:

local username = vim.fn.system("whoami"):gsub("\n", "")

vim.api.nvim_create_autocmd({"BufEnter", "BufWinEnter"}, {
    pattern = {"*.md"},
    callback = function()
        local workspace_map = {
            ["user1"] = "work",
            ["user2"] = "personal",
        }

        local workspace = workspace_map[username] or "user2"
        vim.cmd("ObsidianWorkspace " .. workspace)
    end,
    desc = "Auto-switch Obsidian workspace based on username"
})

my question is can i migrate this to the event object in my config:

return {
    "epwalsh/obsidian.nvim",
    version = "*",  -- recommended, use latest release instead of latest commit
    lazy = true,
    ft = "markdown",
    -- Replace the above line with this if you only want to load obsidian.nvim for markdown files in your vault:
     event = {
        -- BufEnter <-- PLACE ABOVE CODE HERE?
    },
    -- Optional, configure key mappings. These are the defaults. If you don't want to set any keymappings this
    -- way then set 'mappings = {}'.
    mappings = {
        -- Overrides the 'gf' mapping to work on markdown/wiki links within your vault.
        ["gf"] = {
            action = function()
                return require("obsidian").util.gf_passthrough()
            end,
            opts = { noremap = false, expr = true, buffer = true },
        },
        -- Toggle check-boxes.
        ["<leader>ch"] = {
            action = function()
                return require("obsidian").util.toggle_checkbox()
            end,
            opts = { buffer = true },
        },
        -- Smart action depending on context, either follow link or toggle checkbox.
        ["<cr>"] = {
            action = function()
                return require("obsidian").util.smart_action()
            end,
            opts = { buffer = true, expr = true },
        }
    },
    dependencies = {
        -- Required.
        "nvim-lua/plenary.nvim",

        -- see below for full list of optional dependencies 👇
    },
    opts = {
        workspaces = {
            {
                name = "personal",
                path = "/Users/<user>/path/to/vault",
            },
            {
                name = "work",
                path = "/Users/<user>/worknotes",
            },
        },
    },
}

note that this config doesn't work as is. I need to comment out the `workspaces.personal" because that path doesn't exist on my work machine and as a result I get errors in neovim
