Redirect to calling application when click the button

[GentleCalf]

So I just chatted to one of line(one of social media) official accounts and they send me a message then when I clicked the button "Call us" it redirected me to my default calling application on my phone and filled out their number. Does anyone know how to do the same thing ?

I can't tell you exactly because this forum does not like the example I typed so Google "URL Scheme for Phone Call"

Which email client are you using?  If it's Outlook this shows you how to do it.
