add Early Access google fonts

Hello maam/Sir

I’ve puchased ‘Fortuna – WordPress Template’

and I understand its included of ‘Revolution Slide’
I’d like to use ‘Early Access google fonts’ on ‘Revolution Slide’

I tried to put this URL (https://www.google.com/fonts/earlyaccess) into ‘Global setting -> Font Loading URL:’
And I went into ‘Slide Editor’ and tried to check in Font list. still only ‘google fonts’

Pls help me out. If I need to ask somewhere else. Pls let me know.

Thank you.
