Logging into Jira Cloud with Okta SAML integration with a non-Okta account

As above really - we have a Jira cloud instance that we have linked to Okta - however, I can’t seem to find a way to authenticate to Jira with a Jira account that doesn’t have a corresponding Okta account as the login always forwards to the Okta login page.

This need arose because Zapier has released a new Jira plugin and I wanted to authenticate that with the “group” account we have created in Jira, which we don’t have an Okta account for.

Is this even possible? Does anyone have any suggestions?

Thanks in advance
