Real Madrid has many forwards at a much better level than Rodrygo, making it a bit more difficult for him to break into the starting lineup. However, I'm sure Xabi Alonso will give him a chance, even if it's not as a starting player, because next season Real Madrid will play many matches, so players will be needed to fill certain positions. When he gets that chance, it will be a chance to showcase his individual qualities, and Rodrygo will gradually become an important part of the squad. Patience is the key because if you don't want to go to another club, what you need to do is improve your quality to be better.
Rodrygo is on the bench because the competition at Real is very high, but this does not mean that he will not play, as injuries happen and Real will be competing in different tournaments, which requires player rotation. Alonso is not counting on Rodrygo, but Rodrygo wants to play only for Real, so he will have to accept the conditions that exist now. I doubt that another club will be able to buy him with such a transfer fee, it seems to me that the price is too high.
