svg image not supported

hello team,

I’m using the oceanwp theme and I couldn’t upload SVG image on a website. getting an error “Sorry, you are not allowed to upload this file type.”

tried following ways with no success.
1. installing plugin for SVG Support.
2. adding define ('ALLOW_UNFILTERED_UPLOADS', true); in wp-config.php file
3. tried the below code as well.

function fix_mime_types($mime){
	$mime['svg']='image/svg+xml';
	return $mime;
}
add_filter('upload_mimes', 'fix_mime_types');

please help me with the solution ASAP.
