Cannot access management API (Logto Self Hosted)

[mammutserver]

I am trying to access the Logto Management API but I can't fetch the access token. I created a M2M application and used the application id and secret.

Code:

const response = await ky.post("https://logto.mydomain.de/oidc/token", {
    headers: {
      "Content-Type": "application/x-www-form-urlencoded",
      Authorization: `Basic ${Buffer.from(
        `${applicationId}:${applicationSecret}`,
      ).toString("base64")}`,
    },
    body: new URLSearchParams({
      grant_type: "client_credentials",
      respource: "https://logto.mydomain.de/api",
      scope: "all",
    }),
});
