You can link your own custom domain to the apps. This means that the app will be available on myapp.example.com instead of myapp.notionapps.com, making it easier to promote the app with your branding when sharing it with others.
Note: Subdomains under a root domain count as a single custom domain. For example, blog.mydomain.com and sales.mydomain.com will be counted as one custom domain.
However, if you have two apps, one linked with mydomain.com and the other with myseconddomain.com, these will be counted as two custom domains.
