Snapchat on Iphone, Its accessibility

I try using snapchat on I-phone SE 2020. but till now, I didn't find any fruitful results. I can take snaps, but cannot view the ones other people send to me. I can send messages, but It's hard viewing what other people texted to me. It's tough locating different chats. also, map, stories and spotlight tabs are not accessible. I have tried using screen recognition alongside voiceover, but it did not work well.
Can anyone provide any sollution of it? since snapchat is very important app these days, inavailability of accessibility makes things chalanging.
