Adding/Accessing Site Logo in Header

I should preface this with saying that I am working in CampusPress for higher ed. Since it’s a closed environment, we’re a bit limited on what plugins we have access to and what we can do in the theme’s CSS and PHP.

We made the switch from Tiny Forge to Tiny Framework last month, and are working to brand it for users at our institution. However, we no longer see the Logo option for the header under the Customize settings in the admin.

In reading the documentation, it looks like this can only be restored by using a 3rd party plugin (Site Logo), which we don’t have access to on the CampusPress environment. Is this an accurate assessment, or are we missing something?

If this functionality has effectively been eliminated by the exclusion of the Site Logo plugin on CampusPress, I understand. I just need final confirmation.

Thanks!
