I have a choice column in dataverse for Teams. How can I update / add items, from a power app, to the possible set of choices?

Patch('My Choice Column Options', Defaults(), {Value: "Choice 4"})
I'm trying to do something like the above, but I'm just getting red squiggle errors.
Is it not possible to update a set of choice other than manually editing it from the table? For this type of situation is the solution to create a new table and use a lookup column / relationship ?
