Most common setting_slugs that can be updated for a seat are:

seat-reservation-max-length - A maximum length of a single reservation on this seat in ISO 8601 duration format. For example "PT2H" represents 2 hours.
seat-reservation-types-allowed - What kind of reservation types are allowed for this seat. Represented as a string array. Possible reservation types and their explanations are:
hot - A short term reservation that goes at max to the end of the day.
hoteled - A long term reservation that has a termination date.
~~assigned~~ -~~ A long term reservation that doesn't have a termination date. Instead it's recurring forever on all days.~~ Deprecated use shared instead
shared - A long term reservation that is recurring on only specific days, not all days in a week.

This endpoint will allow you to update allowed reservation types for a seat with only a single string value inside for all types that are not the shared type. So for example ["hot"] or ["hoteled"] or ~~["assigned"]~~.
For shared types, the array must have two elements. Either ["assigned","shared"] or ["hoteled","shared"].
["assigned","shared"] - Means that this seat should have a recurring shared reservation on specific days, but on all the other days this desk is not reservable by others.
["hoteled","shared"] - Means that this seat should have a recurring shared reservation on specific days, but on all the other days this desk is reservable by others.
