I need to modify the placeholder in Swagger. The current placeholder matches the one specified in property for swagger . How can I resolve this issue?

Question

In the image provided, the property is defined as recipient[name], resulting in the usage of the same placeholder Could you please review the code I've referenced? I'm looking to make adjustments to acquire a different placeholder. Are there any specific changes needed for this purpose?

I'm hopeful that my issue will be resolved as anticipated; I simply need a different placeholder.
