Privilieges escalation with ansible using bastion/jump server - ansible

Question

Is using:
become: true
become_user: root
Something that is ignored when using jump host ? I'm connecting to my destination server using:
"ANSIBLE_SSH_COMMON_ARGS": "-o ProxyCommand='ssh -p 22 -W %h:%p -q user#ip_obfuscated -i /home/semaphore/.ssh/jump.priv'"
The whole connection when i run debug looks like:
<ip_obfuscated> SSH: EXEC ssh -vvv -C -o ControlMaster=auto -o ControlPersist=60s -o StrictHostKeyChecking=no -o 'IdentityFile="/tmp/semaphore/access_key_136706914"' -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o 'User="terraform"' -o ConnectTimeout=10 -o 'ProxyCommand=ssh -p 22 -W %h:%p -q user#ip_obfuscated -i /home/semaphore/.ssh/jump.priv' -o 'ControlPath="/tmp/semaphore/.ansible/cp/1713c02767"' ip_obfuscated '/bin/sh -c '"'"'( umask 77 && mkdir -p "` echo /home/terraform/.ansible/tmp `"&& mkdir "` echo /home/terraform/.ansible/tmp/ansible-tmp-1668542130.3374832-2167-135826106011908 `" && echo ansible-tmp-1668542130.3374832-2167-135826106011908="` echo /home/terraform/.ansible/tmp/ansible-tmp-1668542130.3374832-2167-135826106011908 `" ) && sleep 0'"'"''
Which works just fine, but I'm always connected only as an simple user... I can't escalate the privileges... look at this result:
---
- name: Remove user from Linux server
hosts: all
become: true
tasks:
# Use whoami to determine the current user
- name: Determine current user
shell: whoami
register: current_user
# print the current user
- name: Print current user
debug:
msg: "Current user is {{ current_user.stdout }}"
- name: Determine current user
shell: sudo whoami
register: current_user2
# print the current user
- name: Print current user
debug:
msg: "Current user is {{ current_user2.stdout }}"
Result:
9:12:34 PM

I'm using up to date ansible.
I tried so many combinations of become, become_user, become_method... set it globally, set it on task it self, even in inventory... no idea why it wont become root on its own...
