根据在 Azure B2C 自定义策略中使用声明解析器的其他输入声明设置输入声明的值

Question

I have the below two input claims

<InputClaim ClaimTypeReferenceId="isAccessFlow" DefaultValue="{OAUTH-KV:access_flow}" AlwaysUseDefaultValue="true"/>
<InputClaim ClaimTypeReferenceId="prompt"  DefaultValue="select_account"/>

I want to assign the value for 'prompt' input claim as 'select_account' only when the isAccessFlow value is not true. I am unable to figure out how to write input claim transformations in this case to achieve the requirement.
