Sharepoint Background Section Image

[FabioMFP85]

Hello.
I need help.
I am working on an Asp.Net Core C# project, exporting a template from a model site, but I have a problem. The model site uses a background section, and I cannot export the image applied to it.
To export the model site, I use Get-PnPSiteTemplate.

Is there any parameter to export the applied image so that when applying the template to another site, it does what is intended?

Or is there any way to edit a background section and apply the background image?
Thank you.
