There are three things to try. Only the first will help you for immediate use.
Convert
You can convert the Heic files to jpeg or png, then use that file in Adobe Express. This is the best choice for immediate use on existing Heic files.
"If you open an HEIF image in Photos or Preview on your Mac, choose File > Export, then choose a format such as JPEG or PNG before saving."
Disable
For future images, you can disable Heic on your iPhone:
"Though capturing in HEIF and HEVC format is recommended, you can set these devices to capture media using the older formats, which are more broadly compatible with other devices and operating systems:
- Go to Settings > Camera.
- Tap Formats.
- Tap Most Compatible. This setting is available only on devices that can capture media in HEIF or HEVC format, and only when using iOS 11 or later, or iPadOS.
- All new photos and videos will now use JPEG or H.264 format. To return to using the space-saving HEIF and HEVC formats, choose High Efficiency."
See this help page from Apple for details:

Feature request
A third thing you can do is to make a feature request on UserVoice where the product developers will see it. If it is ever implemented, it won't be immediate.

Also, the weblink posted earlier ( https://helpx.adobe.com/express/system-requirements.html ) only shows devices you where you can use Adobe Express. It does not tell you anything about file formats and Heic.
