Description

When using the options example here, TypeScript gives the following error when using ack:

TS2345: Argument of type '{ options: Option[]; }' is not assignable to parameter of type '(Without<MessageOptions, OptionGroups<MessageOptions>> & OptionGroups<MessageOptions> & Without<...> & OptionGroups<...> & Without<...> & OptionGroups<...>) | (Without<...> & ... 4 more ... & BlockOptions) | undefined'.   

Types of property 'options' are incompatible.     

Type 'Option[]' is not assignable to type '{ text: string; value: string; }[] & { label: string; value: string; }[] & Option[]'.   
Type 'Option[]' is not assignable to type '{ text: string; value: string; }[]'.         
Type 'Option' is not assignable to type '{ text: string; value: string; }'.       
Types of property 'text' are incompatible.
Type 'PlainTextElement | MrkdwnElement' is not assignable to type 'string'.
Type 'PlainTextElement' is not assignable to type 'string'.

This is fixed by the following cast, which shouldn't be necessary, but is:

ack as AckFn<{ options: Option[] }>

I believe this has to do with the XOR in AckFn<XOR<BlockOptions, OptionGroups<BlockOptions>>>
