Property '"siteKey"' is incompatible with index signature

Question

I have been to trying to use your ngx-turnstile library for integrating the captcha for our project. After installing the "npm install ngx-turnstile --save", I have included in the app.module.ts file and imported in the app.module imports Array. Immediately after installing it get this error displayed.

how we can solve this problem We wanted to try your library, but there is no proper documentation of how exactly it can be used in the angular project. There are a couple of examples, but those are not working.

here is the ng version
