or....otherwise (in the same sentence)

Hi

We're committed to the project. We wouldn't be here otherwise.

Taken from https://www.oxfordlearnersdictionaries.com/definition/english/otherwise?q=otherwise

Can I merge the two sentences with 'or'? Would it be wrong or uncessary to use 'or' with 'otherwise' in the same sentence?

If you use "or", remove "otherwise".
