The temporary folder is not cleaned

Congratulations for the plugin, it works well

I discovered the following problem:
When I export the site,
a temporary folder is created inside wp-upload

When the plugin finishes the export,
the folder remains full, creating space problems

I use another plugin to backup the site: UpdraftPlus
which sends the temporary folder in the backup on cloud, thus taking up double the space :-(

Could you empty the folder?
Could you choose [this temporary folder](https://developer.wordpress.org/reference/functions/get_temp_dir/) ?
