Is there a Font license with a purchased theme ?

Hello, I bought a theme ’ Leo Fashion Store’ a couple of years ago. And kept the font ‘Brandon’ used in the theme.
Now the author of the font is asking me my license key for using it.
And can’t find any font license in the package downloaded from themforest.
Do I need to buy one ? Or the font license should have been already in the theme I purchased ?
Thank you

Please ask it directly to the author of your purchased theme, the theme author will let you know.
