Keep font when extracting a visual

Hi all,

I have a custom theme with my organization font. It works perfectly on my reports evrything is ok.

But when I exctract my visual in the app to put them in a presentation, I have this Times New Roman font...

Is it possible to keep my theme font?

And if it's not, because it must uses native Power BI fonts, can I choose what default font it has to use when copying the visuals?

Edit: it is due to the fact that power bi uses a default font when extracting a visual or a report. See here: https://docs.microsoft.com/en-us/power-bi/consumer/end-user-powerpoint#:~:text=When%20exporting%20to%20PowerPoint%2C%20if%20the%20report%20uses%20a%20custom%20font%2C%20that%20font%20will%20be%20replaced%20with%20a%20default%20font.

So my question is How to set a default font in the json them file?

Thanks
