Remote access software question

Hello all!

So the owner of the company I work for is having an issue with Chrome and needs me to remote into her system since she’s over 3000 miles away from us.

Since this is a one off situation, what would you recommend that’s free in order for me to access her pc?

I’m thinking Team Viewer, but I’m open to something easier since she’s not the greatest with PCs/technology.

Thanks in advance!
