Thinking about attending a mosque prayer - am I welcome?

Assalamu alaikum, I’ve just moved into an area where a new mosque is nearby, and I’ve noticed they have regular prayer timings. I’ve been feeling quite nervous but would really love to experience one of the prayers. I'm wondering if it's okay since I’m not Muslim yet - if it is, which prayer time would be best for a newcomer? Also, I’m a woman and I know I should dress modestly and cover my hair. I recall reading that women and men usually pray in separate spaces. Would it be okay to kindly ask one of the sisters there to show me where I can sit and maybe guide me a bit? I don’t want to do anything that might be seen as disrespectful.
