FontAwesomeIcon throwing "Could not find icon" when using with Pro regular sharp icons

[sampolahtinen]

Describe the bug
When trying to use FontAwesomeIcon react component with paid sharp regular icons, an error is being thrown in the console saying Could not find icon

Reproducible test case

1. import { faCircleExclamation } from '@fortawesome/sharp-regular-svg-icons'
2. Add it to the libary

import { library } from '@fortawesome/fontawesome-svg-core'
library.add(faCircleExclamation)

3. Attempt to use the icon:

<FontAwesomeIcon icon="circle-exclamation" />

4. Error in the browsers console:

It seems that the FontAwesomeIcon component is trying to run a lookup using wrong prefix fas. The prefix of this icon is fasr

Furthermore, it seems that the IconPrefix type does not include fasr:

export type IconPrefix = "fas" | "far" | "fal" | "fat" | "fad" | "fab" | "fak" | "fass" ;

, which means that following syntax throws static TS error:

<FontAwesomeIcon icon={{ prefix: `fasr`, iconName: `circle-exclamation` }} />

Expected behavior
Should be able to render the icon.

Package versions

"@fortawesome/fontawesome-common-types": "^6.3.0",
"@fortawesome/fontawesome-svg-core": "^6.3.0",
"@fortawesome/free-regular-svg-icons": "^6.3.0",
"@fortawesome/free-solid-svg-icons": "^6.3.0",
"@fortawesome/react-fontawesome": "^0.2.0",
"@fortawesome/sharp-regular-svg-icons": "^6.3.0",

Thanks in advance! Let me know if you need more information!

This bug also applies to the library @fortawesome/pro-regular-svg-icons.

So basically pro icons can not be used with FontAwesomeIcon

Any movement in regards to fixing the issue?

@sampolahtinen Is this specific to version 6? We are successfully using pro icons from Font Awesome V5 via react-fontawesome...but now you have me nervous about our planned migration to v6.
