For example, given the file

shell> cat /tmp/test.json 
{
"access_token": "xxxxxxxxxx",
"expires_in": 43200,
"token_type": "xxxxxx"
}

The value of *result.stdout* is *AnsibleUnsafeText*. What you see
depends on the callback. The below play

shell> cat pb.yml
- hosts: all
  tasks:
    - command: cat /tmp/test.json
      register: result
    - debug:
        var: result.stdout

gives JSON with the default callback

shell> ANSIBLE_STDOUT_CALLBACK=default ansible-playbook pb.yml
  ...
ok: [localhost] => {
    "result.stdout": {
        "access_token": "xxxxxxxxxx",
        "expires_in": 43200,
        "token_type": "xxxxxx"
    }
}

The same task gives YAML with the yaml callback

shell> ANSIBLE_STDOUT_CALLBACK=yaml ansible-playbook pb2.yml
  ...
ok: [localhost] => 
  result.stdout:
    access_token: xxxxxxxxxx
    expires_in: 43200
    token_type: xxxxxx

You can test the type of the attribute *stdout*

    - debug:
        var: result.stdout|type_debug

gives

  result.stdout|type_debug: AnsibleUnsafeText


>  filter the access token alone

Convert the text to dictionary and get the *access_token* as well.
It's up to you where you put the vars

  vars:

    test_data: "{{ result.stdout|from_json }}"
    access_token: "{{ test_data.access_token }}"

Example of a complete playbook for testing

shell> cat pb.yml
- hosts: all

  vars:

    test_data: "{{ result.stdout|from_json }}"
    access_token: "{{ test_data.access_token }}"

  tasks:

    - command: cat /tmp/test.json
      register: result
    - debug:
        var: result.stdout
    - debug:
        var: result.stdout|type_debug
    - debug:
        var: test_data|type_debug
    - debug:
        var: test_data
    - debug:
        var: access_token
