Azure/Entra SSO - multiple tenants?

[AndyAIT]

So I know how to set up the SSO for Entra/Azure AD and it's working well. However, I have a scenario where I'd like to allow 3-4 team members from a client, who have their own Entra tenant to access my MC instance, but using their Entra logins.

Is this possible, without breaking our internal SSO? IE - can I have multiple entries in the config.json for different applications?

to throw it out there could I just replicate this:
"authStrategies": {
"azure": {
"newAccounts": true,
"clientid": "be4aadd3-77b8-4e55-af8a-4b8e2d994cb5",
"clientsecret": "NP0XXXXXXXXXXXXXXXXXXX",
"tenantid": "18910a48-e492-4c49-8043-3449f7964bd6"
}

but change "Azure" to "ExternalCompany" and put the relevant details there, or will it only be able to auth to one?

Unfortunately not, you can only have one config option

I'm guessing as i don't use entra, can't you like invite a user into your entra?
