Check the below code and edit it accordingly for your requirement.

trigger ContentDocumentLinkTrigger on ContentDocumentLink ( after insert ) {
    
        
    Set < Id > setAccIds = new Set < Id >();
    Map < Id, Id > mapAccIdContDocId = new Map < Id, Id >();
        
    for ( ContentDocumentLink objCDL : trigger.new ) {
        
        String strEntityId = objCDL.LinkedEntityId;
        
        if ( String.isNotBlank( objCDL.LinkedEntityId ) && strEntityId.left( 3 ) == '001' ) {
        
            setAccIds.add( objCDL.LinkedEntityId );
            mapAccIdContDocId.put( objCDL.LinkedEntityId, objCDL.ContentDocumentId );
            
        }
        
    }
    
    if ( setAccIds.size() > 0 ) {
    
        CustomNotificationType notificationType = [SELECT Id FROM CustomNotificationType WHERE DeveloperName = 'Desktop'];
                    
        Messaging.CustomNotification notification = new Messaging.CustomNotification();
        Set < String > recipientsIds = new Set < String >();
        notification.setTitle( 'File Attached to your Account' );
        notification.setNotificationTypeId( notificationType.Id );
    
        for ( Account objAcc : [ SELECT Id, OwnerId FROM Account WHERE Id IN: setAccIds ] ) {
        
            notification.setBody( 'File Id is ' + mapAccIdContDocId.get( objAcc.Id ) );
            notification.setTargetId( objAcc.Id );
            recipientsIds.add( objAcc.OwnerId );
            notification.send( recipientsIds );
        
        }
    
    }

}
