issue: submitValues is of type undefined unless strictNullChecks is true, or explicit use of TTransformedValues

Version Number

7.44.3

Codesandbox/Expo snack

https://codesandbox.io/p/sandbox/determined-haze-c93dmv?welcome=true

Steps to reproduce

1. Install project using react-hook-form 7.44.3
2. See that submitValues is of type undefined (why?)

Workarounds I come up with:

4. Change tsconfig's strictNullChecks to true
5. See that submitValues is of type FormValues

However, on some big projects, one cannot simply turn on strictNullChecks.

6. Change strickNullChecks back to false
7. Change useForm call to useForm<FormValues, any, FormValues>({
8. See that submitValues is of type FormValues again

Other fix:
9. Revert to previous of useForm: useForm<FormValues>({
10. Downgrade to react-hook-form 7.43.9
11. See that submitValues is of type FormValues again

Expected behaviour

submitValues should be of type FormValues, however it is of type undefined.

What browsers are you seeing the problem on?

Additionally, I don't understand what the 3rd parameter TTransformedValues of useForm is used for. I couldn't find any documentation regarding this.
