Argument transaction tx with prisma accerlate typescript error

Yo yo, so i have a very long transaction that i am wanting to break up, just for easier maintance. So i want to pass the transaction func as argument however i am getting typescript type mismatch. ( am guessing because of prisma accerlate) example: 
const trans = await prisma.$transaction(async (tx) => {
            const isTransaction = await exampleFuncUsingTx(tx);
        });


const exampleFuncUsingTx = async (tx: Prisma.TransactionClient) => {
}
const trans = await prisma.$transaction(async (tx) => {
            const isTransaction = await exampleFuncUsingTx(tx);
        });


const exampleFuncUsingTx = async (tx: Prisma.TransactionClient) => {
}
Doing above, ill get this error: 
Argument of type 'Omit<DynamicClientExtensionThis<TypeMap<InternalArgs<{ [x: string]: { [x: string]: unknown; }; }, { [x: string]: { [x: string]: unknown; }; }, { [x: string]: { [x: string]: unknown; }; }, { [x: string]: unknown; }> & { result: {}; model: { $allModels: { ...; }; ... 56 more ...; zzz_invoice: { ...; }; }; query: {}; c...' is not assignable to parameter of type 'TransactionClient'.

I suppose my main question, is it safe for me to just make this assumption? 
tx:  as unknown as Prisma.TransactionClient
