Basic read from Ethereum smart contract into Google Sheet via Apps Script function

Job ID: 30955160

Budget: £20 – £250 GBP

Hello, I want to create a google sheets apps script function that lists the constituents and % allocations of this smart contract: https://etherscan.io/token/0x1494CA1F11D487c2bBe4543E90080AeBa4BA3C2b#readContract

The constituents and allocation %s are listed here: https://www.indexcoop.com/mvi

For example, as of the 26th July, one of the constituents is AXS and the % allocation is 26.61%.

I believe the relevant function to call on the smart contract is getPositions, but I don't know how to read from a smart contract in Google Apps Script.
