Escape Special Char in Ansible

Need help with escaping special characters for lineinfile

I'm trying to do the following to simply change the bash prompt

- name: Editing bashrc to change bash prompt
  lineinfile:
    path: /etc/bashrc
    regexp:  "export PS1='\[\033[01;31m\]\u@\h\[\033[01;34m\] \w #\[\033[00m\]'"
    line:  "export PS1='\[\033[01;31m\]\u@\h\[\033[01;34m\] \w #\[\033[00m\]'"

but as you can see, the regexp: value is full of special characters that I need to escape. Is there a simple way to escape the entire line? Or maybe there's another way I should be doing this?

i did try to do the following: 1 : add the text in a variable for re-use

- hosts: ssh
  vars:
    export: "export PS1='\[\033[01;31m\]\u@\h\[\033[01;34m\] \w #\[\033[00m\]'"
- name: Editing bashrc to change bash prompt
  lineinfile:
    path: /etc/bashrc
    line: "{{ export }}"

and even with !unsafe for raw_strings

2. To escape special characters within a regex, use the “regex_escape” filter:

{{ '^f.o(.)$' | regex_escape() }}

maybe my syntax is not goot but i keep having an issue:

The offending line appears to be:

  vars:
    export: "export PS1='\[\033[01;31m\]\u@\h\[\033[01;34m\] \w #\[\033[00m\]'"
                         ^ here

Thanks!
