I am trying to test an upgrade proposal on a MainnetFork network. I have created this Fork using Tenderly. I submitted the proposal to Defender, but now I am unsure how to 'accept' the proposal in such a way that it will be applied to the fork and not actual mainnet.
I tried adding the fork network in the defender settings, but i get this error
" there is already a public network with chain id 0x1 " with makes no sense to me . Obviously yes i know that. Its a fork network.
How can i accompliish my ultimate goal of applying the OZ defender proposal to the fork network ?
