href not working in salesforce one app

I have created a community in salesforce and i wanted to navigate to other apps when user clicks call or email button. I created a lightning web component and I used href="mailto:(email here)" and href="tel:(phone here)" but this doesn't work if I open the community in salesforce one app. It does work on Desktop and Mobile browsers. What might be the problem here?

Thanks

<a href="tel:(Number here)">
                        <img
                          alt="Phone"
                          src={phonePinkIcon}
                          title="Phone"
                        />
                      </a>
                      <a href="mailto:(Email here)">
                        <img
                          alt="Email"
                          src={emailPinkIcon}
                          title="Email"
                        />
                      </a>
