You can also provide a function to run when `autoload = true` but there is no session to be loaded:
```lua
require("persisted").setup({
autoload = true,
on_autoload_no_session = function()
vim.notify("No existing session to load.")
end
})
```
Autoloading can be further controlled for certain directories by specifying `allowed_dirs` and `ignored_dirs`. Autoloading can be further controlled for certain directories by specifying `allowed_dirs` and `ignored_dirs`.
