How does Polylang pick up translatable strings from my custom theme files?

I have created a basic theme from scratch and I have wrapped all the translatable texts in the __e() function.

I have installed the Polylang plugin to have the website translated into Spanish but after going their their documentations and reading about it, I have understood that

1. I need to change all my _e() functions to pll_e() functions

2. Register every single string inside my php files using the pll_register_string() function, meaning if i 500 translatable strings in my theme, I have to repeat the same strings and pass them as parameters inside the pll_register_string() function as well 500 times so that Polylang can pick them up and display them on the fronted and on the backend under Languages>String translations.

Is this how this is done or am I doing something very wrong?

Thank you
