Change password reset form

Hi there…
I’m trying to edit the password reset form. I’ve no experience with PHP.
and so I checked this doc (https://docs.ultimatemember.com/article/119-overriding-default-ultimate-member-profile-templates).

I did the same thing as mentioned in the doc.
wp-content/themes/ultimate-member/templates/password-reset.php

but it’s not working for me…

Changes I need:
1. Change text [To reset your password, please enter your email address or username below.]

2. Change Button Text [reset my password]

3. change the text after submitting reset my password [If an account matching the provided details exists, we will send a password reset link. Please check your inbox.]

4. Reset form input field placeholder [Enter your username or email]

***

Changes I did in this folder (wp-content/themes/ultimate-member/templates/password-reset.php)

1. Changed text [Please enter the email address you’d like your password reset information sent to]

2. Changed Button Text [Request Reset Link]

3. changed the text after submitting reset my password [If the information provided matches our records, then a link will be sent to your email. This link will expire in 24 hours.]

4. Reset form field placeholder [Enter your email]….I couldn’t find this field. As I can see in this template file this is a field I’m not sure [$fields = UM()->builtin()->get_specific_fields( ‘username_b’ );] this field should accept only emails not username. how to modify this?

Let me know what I’m doing wrong….why’s the template not overriding?
