Is there a way to make DEVONthink browser say it's Safari?

I want to load in the DEVONthink browser a task management web page (Trello). That site tells me that my browser isn’t compatible. But since DEVONthink is using WebKit, it should just work, if DEVONthink reports the same UA string as Safari.

Is there a way to make DEVONthink just tell sites that it’s Safari?

Thanks,
Eric
