I distinctly remember yum/dnf should be using a loop. Forget why but it's recommended. Here's a snippet from my playbook. Simply make the vars as you need and run.

  - name: Install flathub as remote
    ansible.builtin.shell:
      cmd: flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
    tags:
      - apps

  - name: Install flatpak apps
    community.general.flatpak:
      name: "{{ item }}"
      state: present
    loop: "{{ flatpaks }}"
    tags:
      - apps

  - name: Remove some default unused packages
    ansible.builtin.dnf:
      name: "{{ item }}"
      state: absent
      update_cache: no
    loop: "{{ remove }}"
    ignore_errors: true
    tags:
      - apps

  - name: Install our packages
    ansible.builtin.dnf:
      name: "{{ item }}"
      state: present
      update_cache: yes
    loop: "{{ rpms }}"
    ignore_errors: true
    tags:
      - apps```
