Appium - Intall iOS apps from a testflight public url

Hi, I’m trying to install / run an iOS app from a test flight public url when using appium desktop but get the following error when starting the session:

“An unknown server-side error occurred while processing the command. Original error: Could not install app: ‘ENOTDIR: not a directory, scandir ‘/var/folders/[DIRECTORY_PATH]/[RANDOM_GENERATED_CODE].app’’”

The desired capabilities I provided to appium desktop are shown below:

{
“automationName”: “XCUITest”,
“platformName”: “iOS”,
“deviceName”: “[DEVICE_NAME]”,
“platformVersion”: “13.3”,
“xcodeOrgId”: “[XCODE_ORG_ID]”,
“xcodeSigningId”: “iPhone Developer”,
“udid”: “[DEVICE_UDID]”,
“bundleId”: “[APP_BUNDLE_ID]”,
“updatedWDABundleId”: “[WEDRIVER_AGENT_RUNNER]”,
“app”: “https://testflight.apple.com/join/[RANDOM_GENERATED_CODE]
}

Does appium support this functionality? If so what am i missing?

Which response is returned for that URL (body and headers)? Also, the full server log is needed
