Type is declared but never used.ts (6196)

I am using the abi from an open source contract and when I create types with typechain it has a line `import type { PayableTransactionObject }` This gives me the error `'PayableTransactionObject' is declared but never used.ts (6196).` How can I avoid this without making my tsconfig less strict?

At the moment I am just deleting the line which makes everything work. However this means I need to track the file in git which goes against the recommendation of making typechain part of the build process.
