I don't think it's possible as

react-i18next

is a library for react framework. Keep in mind, that your Cypress tests are kinda another application that is being run to evaluate the react one. These two pieces do not share a state or anything like this. They are two independent processes but within the same repository. Also, if I might suggest, I'd not search elements by text if it's possible and that's what you're trying to do. Instead, try to use a css locator or ask the developers to add a custom one only for testing purposes. I hope it makes sense
