Deploy multiple micro-frontend into single static web apps

Hi,

Can I deploy multiple micro-frontend into single static web apps?

For example, Suppose my static web apps url is https://my.azurestaticapps.net/, and I hope my micro-frontend-apps can mapping to different sub route in static web apps.

- myapp1 -> https://my.azurestaticapps.net/app1/
- myapp2 -> https://my.azurestaticapps.net/app2/
- myapp3 -> https://my.azurestaticapps.net/app3/

When I deploy only app1, it's perfect.
But after app2 deployment, app1 content was disappear.

Is there any way to keep all the files preserve when multi deployment?
Thanks.
