## Summary\nToast shown after removing an NFT appears in the middle of the viewport on the Home > NFTs tab.\n\n## Expected\nUse the standard toast component so the confirmation appears at the bottom with correct styling.\n\n## Jira\nhttps://consensyssoftware.atlassian.net/browse/MDP-666

Start by reproducing NFT removal from the Home > NFTs tab and trace the toast shown after removal. Compare it with the standard toast component; done means the confirmation appears at the bottom of the viewport with the expected styling.
