How to change "parse_cli_textfsm" to reference template folder in role folder in Ansible?

Question

GOAL

• I want to create a portable role folder that utilizes textfsm templates in role directory.
• Directory structure

$ tree
.
├── ansible.cfg
├── hosts.ini
├── out_pb1
├── pb1.yml
├── roles
│   ├── command_facts
│   │   ├── tasks
│   │   │   └── main.yml
│   │   ├── templates
│   │   │   └── textfsm   // I want this
│   │   └── vars
└── templates
    └── textfsm   // created for testing

PROBLEM

• parse_cli_textfsm is referencing to templates/textfsm instead of roles/command_facts/templates/textfsm
• The goal is portability so specifying full path is not considered.

ATTEMPTS TO FIX (FAIL)

• Executes pb1.yml
• Error shown as below if I deleted templates/textfsm in the pb1.yml directory.

$ ansible-playbook pb1.yml -u username -k
(omitted)
TASK [command_facts : set_fact]
fatal: [target]: FAILED! => {"msg": "unable to locate parse_cli_textfsm template: /templates/textfsm"}

• I tried to utilize system variable role_path that is {{ raw_output.stdout | parse_cli_textfsm('{{ role_path }}/templates/textfsm') }} but it is not working. {{ role_path }} turns into a normal string.

$ ansible-playbook pb1.yml -u username -k
(omitted)
TASK [ixrs_facts : set_fact] 
fatal: [target]: FAILED! => {"msg": "unable to locate parse_cli_textfsm template: {{ role_path }}/templates/textfsm"}

FILES

• roles/command_facts/task/main.yml

---
- name: show protocols all
  raw: "show protocols all"
  register: raw_output
- set_fact:
    output: {{ raw_output.stdout | parse_cli_textfsm("/templates/textfsm") }}
- debug: var=output[::]

• pb1.yml

---
- name: testing
  hosts: target
  gather_facts: false
  roles:
    - { role: command_facts }

REFERENCE

• https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#network-cli-filters
• {{ output.stdout[0] | parse_cli_textfsm('path/to/fsm') }}

Use this: parse_cli_textfsm('{{ role_path +“/templates/textfsm“) }}
