[ansible-project] How can I pass variables to command module's argv parameter in Ansible?

[tariver 16]

Greeting!
Asked it on stackoverflow 
<https://stackoverflow.com/questions/75388765/how-can-i-pass-variables-to-command-modules-argv-parameter-in-ansible>,
 
but didn't get an answer, so I'm trying my luck here.

A bit condensed version:
I'm trying to write a role that creates a Redis cluster. At some point I 
must execute redis-cli binary with some parameters:

/usr/bin/redis-cli --user admin --pass mypass --cluster create 
10.226.2.194:6379 10.226.2.196:6379 10.226.2.195:6379 --cluster-replicas 1 
--cluster-yes 

I pass all the required parameters as extra variables when I call the 
playbook with a shell script:

#!/bin/sh ansible-playbook /etc/ansible/playbook-redis.yml -vv \
--extra-vars='redis_admin_user=admin redis_admin_password=mypass' \
--extra-vars='redis_cluster_members="10.226.2.194:6379 10.226.2.196:6379 
10.226.2.195:6379" redis_cluster_replicas=1'

At first I tried the following:

- name: Create Redis cluster
  ansible.builtin.command:
    argv:
      - /usr/bin/redis-cli
      - "--user {{ redis_admin_user }}"
      - "--pass {{ redis_admin_password }}"
      - "--cluster create {{ redis_cluster_members }}"
      - "--cluster-replicas {{ redis_cluster_replicas }}"
      - --cluster-yes

And got error "Unrecognized option or bad number of args for: '--user 
admin'" which is a redis-cli error.

After some experimenting I found out that if I pass the variables in a 
separate line some of them work. So this task works and returns info about 
server.

- name: Get server info
  ansible.builtin.command:
    argv:
      - /usr/bin/redis-cli
      - --user
      - "{{ redis_admin_user }}"
      - --pass
      - "{{ redis_admin_password }}"
      - info 

So the username and password are recognized be redis-cli, but, 
unfortunately not the "redis_cluster_members". The following task:

- name: Create Redis cluster
  ansible.builtin.command:
    argv:
      - /usr/bin/redis-cli
      - --user
      - "{{ redis_admin_user }}"
      - --pass
      - "{{ redis_admin_password }}"
      - --cluster create
      - "{{ redis_cluster_members }}"
      - --cluster-replicas
      - "{{ redis_cluster_replicas }}"
      - --cluster-yes 

returns error "Unrecognized option or bad number of args for: '--cluster 
create'"

I wonder if I'm missing some syntax error or misread the documentation and 
trying to use argv not the way it's supposed to be used?
