Point Multiple Secured Domains to Different apps on Amazon Lightsail Windows Server

I have a domain in GoDaddy and an Amazon LightSail Windows Server 2019. I am trying to point the main domain and subdomain to two different IIS sites. For example.

• example.com to IIS App1
• app.example.com to IIS App2

Well, this scenario is simple enough if I point my domain and subdomain to a static IP by adding an A record. I was able to point.

• http://example.com to IIS App1
• http://app.example.com to IIS App2

but this way my connection was not secure and I wanted to add an SSL certificate.

To add the SSL in LightSail I have done the following.

1. Created DNS Zones in LightSail and point my GoDaddy domain to it
2. Create a static IP in LightSail
3. Created Distribution in LightSail
4. Created SSL Certificate and enabled Custom Domain

Now SSL is successfully installed and I am able to access my main domain but both of the domains point to IIS APP1

• https://example.com to IIS App1
• https://app.example.com to IIS App1

How can I point https://app.example.com to IIS App2 using Amazon LightSail Distribution?

Please note that in IIS APP2 I have added binding for app.example.com for port 80 and 443 and Require Server Name Indication is Checked.
