Can you set up FreeSpoke as a default search engine on iPhone?

here is for spoke app can you set it up as a default search engine on iPhone so yep I was just trying to do some research and if I go to settings of Safari on iPhone and then I select search engine as you can see it's not yet suggested here as a default search engine so you have Google Yahoo bing.go and ecosia but now uh no option of this app um so yeah I don't think it's possible yet maybe this feature is coming soon but that's it I don't also think it's available in Google Chrome app if you have other suggestions leave them in the comments below
