I need mom advice

How long did it take your toddlers to let you know when to go potty? I just started training again my daughter she’s 2yrs 5 . She still doesn’t let me know that she needs to go. So I still have to guess when to take her. Even if I tell her or show her so it’s a little hard. We still have some accidents since we just started but that’s my issue right now that she still doesn’t know how to tell me
