Laravel Validate Array of Files Max Size

My View has an array of file inputs like

<input type="file" name="videos[]" />
<input type="file" name="videos[]" />
...
...

and I want to validate for the total allowable upload size (Eg: Total Allowable Upload limit is 3Mb). I've written the validation like

$validatedData = $request->validate([
     'videos.*' => 'present|file|mimetypes:video/mp4,video/ogg|max:3000',
]);

but this validates 3Mb per video.

I've tried

$validatedData = $request->validate([
     'videos' => 'file|max:3000',
]);

but the validation is not working. Do I have to write a Custom Validation Rule to validate the total uploaded file size limit. Or is there any predefined validation rule? Any help appreciated.

Thank You!
