❓ How to define dynamic requestBody properties?

[Rikj000]

I'd like for users to be able to dynamically provide as many requestBody properties (key/value)
as they need to send to the endpoint in Swagger.

For this particular endpoint, these properties are not static / not always the same.

Example requestBody 1:

foo: "bar",
lorem: "ipsum"

Example requestBody 2:

literally: "anything",
should: "go",
numbers: "123"

Currently I defined 2 static example properties,
however this does not make it clear to users that they can send any and as much properties (key/value) as they need.

How would I go about implementing this dynamically?
Is this even possible right now? (I have my doubts due to swagger-api/swagger-ui#2771)
