1. Select select claim options, remember the claimed amount
2. Send the TX to the connected wallet
3. Change Gas limit in the connected wallet to be at less than a half of the required value
4. Wait till the TX fails
5. Go back, change claimed amount/options
6. Send the TX to the connected wallet

AR: claimed amount for the 1st attempt is displayed in the 'Waiting' modal'
