Crack on with it, she is too old to be in nappies if she has no developmental issues. Two months is ages.
It’s confusing for them when you stop and start, so commit and stick to it. Stay home for a week, to get going.
Take her out and buy some big girl pants (even if you already have some), get her to help you to ceremonially put the nappies away ‘until a baby visits and needs them’.
Ask her where she would like to have her potty and what books she would like to have there.
Take her into the bathroom with you and demo using the loo. Repeat this as you go if she is slow to pick up. She needs to see this as the grown up thing to do.
Put her in pants, always, feeling wet material is part of what will make her want to use the potty.
Put her on it regularly to start with - so regularly the chances of an accident are minimal, reward her for using it.
Once that’s working, put her on it less often and start rewarding her for asking for it and using it. Prompt her regularly to start with.
Once that’s working start a reward chart with a big thing she’s like if she is (more or less) using it successfully for a week.
Talk to your health visitor in a month if it isn’t working, but (unless there is a deeper problem, in which case you need a referral) it will.
