Cannot use 1Password SSH agent from a Mac Mini without biometrics

I was aware of the ssh support in 1Password for some time and today I finally decided to give it a try.

I have some different machines at home (Linux, Windows, Mac) and I decided to start it on my Mac Mini M1 (1st gen).
I was following the instructions here but unfortunately it did not work.

For instance, after setting up GitHub with my key, if I try to

ssh -Tvv git@github.com

I get

debug1: Offering public key: 1password RSA SHA256:... agent
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: 1password RSA SHA256:... agent

Then, in the "1Password Access Requested" dialog, I click in "Authorize".
And then I get

sign_and_send_pubkey: signing failed for RSA "1password" from agent: agent refused operation
debug1: No more authentication methods to try.
git@github.com: Permission denied (publickey).

I've checked some 1Password logs using

less ~/Library/Group\ Containers/2BUA8C4S2C.com.1password/Library/Application\ Support/1Password/Data/logs/1Password_rCURRENT.log

And there I noticed this

INFO  2023-04-30T14:47:04.075 tokio-runtime-worker(ThreadId(21)) [1P:foundation/op-apple/src/biometry_service.rs:308] System biometry info: BiometricStatus { current_policy: BiometricsOnly, current_method: TouchId, current_availability: NotPaired }

My impression is that 1Password's ssh agent is expecting a biometrics confirmation, which does not happen and therefore the connection is disallowed. Important, this is a Mac Mini, and I don't have access to any sort of biometrics...
