I was trying to fix the 'Ensure text remains visible during webfont load' issue from Lighthouse audit for my web application.I have read from many articles about font-display:swap as the solution for this warning. Its working fine for the font I have added in my application.
But am getting this warning for the third party resources like fontawesome and font.gstatic.com.I have attach the screenshot below:

I have added font-awesome icon plugin for my app. And I am founding this fontawesome-webfont inside font-awesome.min.css.
How can I fix this issue? Can someone help me out of this warning?
Thanks in Advance:)
