GitHub actions tag - github-actions

Question

I'm currently trying to allow tags only on the main branch. But I can't seem to get it to work. This is what I currently have but it also triggers the production build if a tag is being put on a develop/release/hotfix branch.. Is there a way to check if the tag has been created on the main branch?
Current YAML:
name: Release to production
on:
push:
branches:
- 'hotfix/**'
tags:
- 'v*'
jobs:
get-version-data:
runs-on: ubuntu-latest
steps:
- name: Get production version from tag
if: ${{ startsWith(github.ref, 'refs/tags/v') }}
id: get_version
run: echo "VERSION=$(echo ${{ github.ref }} | cut -d '/' -f 3 | cut -c2-)" >> $GITHUB_ENV
- name: Get hotfix version from tag
if: ${{ contains(github.ref, 'hotfix') }}
id: split
uses: jungwinter/split#v2
with:
separator: '/'
msg: ${{ github.ref }}
- name: Write hotfix version to env
if: ${{ contains(github.ref, 'hotfix') }}
run: echo "VERSION=${{ steps.split.outputs._3 }}" >> $GITHUB_ENV
- name: Exit if version could not be determined
if: ${{ env.VERSION == '' }}
run: exit -1
- name: Build Number
run: echo "BUILD_NUMBER=$(($GITHUB_RUN_NUMBER + 125))" >> $GITHUB_ENV
outputs:
version: ${{ env.VERSION }}
build-number: ${{ env.BUILD_NUMBER }}
