typescript type of datafile from '@optimizely/optimizely-sdk' is not specific enough ("string | object")

Here is the snippet we use:

import type { Config } from '@optimizely/optimizely-sdk';
type OptimizelyDatafile = Config['datafile'];

When you import the type, you can see its string | object 

which is clearly not good enough for the object type, because in general shape of datafile is at least the following:

export const FALLBACK_DATAFILE = {
 rollouts: [],
 typedAudiences: [],
 anonymizeIP:true,
 variables: [],
 featureFlags: [],
 experiments: [],
 audiences: [],
 groups: [],
 attributes: [],
 botFiltering:true,
 events: [],
 revision:'1',
 version:'4'
};

so clearly the datafile is ought to be more specific than object, can we get it properly typed in its shape, values and all the fields within it too?
