Provision UI studio settings

Hi,
we want to provision UI studio settings during startup. We reverse engineered the relevant settings and succeeded in provisioning ui.main-logo and ui.icon-logo. But we did not succeed in provisioning the colour codes for the theme (ui.studio.themes). According to the value saved via the GUI this is a json-string but it has some kind of strange escaping/quoting and we did not succeed in mapping this to yaml correctly.

Does anyone have a working sample for this scenario?

Thanks!

What exactly do you mean by provisioning in this case?
What changes are you making and where. Did you clone the repository?

Or are you just trying to clone a database?

By provisioning I mean the yaml files for initial database seeding in /server/provision/001_settings. We added another file ui.yaml and tried to add ui.studio.themes-setting there.
