remote signer can't be used with participant matrix

[james-prysm]

i've tried a few ways to use remote signer with the participant matrix but went back to using it in just participant

participants_matrix:
  el:
    - el_type: geth
      el_image: ethpandaops/geth:fusaka-devnet-3
  cl:
    - cl_type: prysm
      supernode: true
      count: 2
      cl_image: gcr.io/offchainlabs/prysm/beacon-chain:latest
      cl_extra_params: [--minimal-config=true]
      use_separate_vc: true
      use_remote_signer: true
      remote_signer_type: "web3signer"
      remote_signer_image: "consensys/web3signer:develop"
      vc_image: gcr.io/offchainlabs/prysm/validator:latest
      vc_extra_params: [--minimal-config=true]

I attempted first to do the above with errors that use_remote_signer is not an attribute

Then I tried using

participants_matrix:
  el:
    - el_type: geth
      el_image: ethpandaops/geth:fusaka-devnet-3
  cl:
    - cl_type: prysm
      supernode: true
      count: 2
      cl_image: gcr.io/offchainlabs/prysm/beacon-chain:latest
      cl_extra_params: [--minimal-config=true]
      use_separate_vc: true
      vc_image: gcr.io/offchainlabs/prysm/validator:latest
      vc_extra_params: [--minimal-config=true]
 remote_signer:
    - remote_signer_type: "web3signer"
      remote_signer_image: "consensys/web3signer:develop"

which didn't seem to work either

it would be great if there was an example using web3signer with participants matrix
