如何增加 moderncv 中联系信息之间的空间？

Question

这是一个简单的例子：

\documentclass[10pt,legalpaper,sans]{moderncv}        % possible options include font size ('10pt', '11pt' and '12pt'), paper size ('a4paper', 'letterpaper', 'a5paper', 'legalpaper', 'executivepaper' and 'landscape') and font family ('sans' and 'roman')

\renewcommand{\familydefault}{\sfdefault}         % to set the default font; use '\sfdefault' for the default sans serif font, '\rmdefault' for the default roman one, or any tex font name

% modern themes
\moderncvstyle{classic}                            % style options are 'casual' (default), 'classic', 'oldstyle' and 'banking'
\moderncvcolor{black}                                % color options 'blue' (default), 'orange', 'green', 'red', 'purple', 'grey' and 'black'

% character encoding
\usepackage[utf8]{inputenc}                   

% adjust the page margins
\usepackage[margin=0.63in]{geometry}
\setlength{\footskip}{10pt}
\usepackage{import}
\nopagenumbers{}

% personal data
\name{FirstName}{LastName}
\phone[mobile]{[phone]}                   
\email{[email protected]}    
\social{https://www.linkedin.com/in/firstname/}
\homepage{firstname.github.io}
