I don't believe there is an Azure service that would allow you to build such for as out-of-the-box capability.
There are several options requiring you to build a custom solution:
Power Apps - this is low-code / no-code service (part of the Power Platform), where you could author the GUI (your form), publish it to your users, and integrate it in the backend with e.g. Power Automate (formerly known as Flow), Logic Apps or similar to process those requests. You can build an interactive app with it, not just a simple form. More info: https://powerapps.microsoft.com/en-us/
