Magento 2 - Add image to category programmatically

Question

I'm trying to create a web service rest to add an image to category, but I can't find the Model method that allow to do this.

I'm looking for something like

addImage of Magento\Catalog\Model\Product\Gallery\Processor

for the category.

Thanks

For category, by default, seem that we cannot do the same, however, we can add the image like this:

/** @var \Magento\Catalog\Model\Category $category **/

$category->isObjectNew(true);
$category->setId(5)
    ->setName('Category 1.1.1')
    ->setParentId(4)
    ->setPath('1/2/3/4/5')
    ->setLevel(4)
    ->setAvailableSortBy('name')
    ->setDefaultSortBy('name')
    ->setIsActive(true)
    ->setPosition(1)
    ->setCustomUseParentSettings(0)
    ->setCustomDesign('Magento/blank')
    ->setThumbnail('media/catalog/category/test.jpg')
    ->save();

With API (not yet test)

/** @var \Magento\Catalog\Api\CategoryRepositoryInterface $category **/

$category->get($categoryId)
         ->setThumbnail('media/catalog/category/test.jpg');
         ->save();
