How to access github package registry from one repo to other under same organization?

Question

I'm working under organization Org which has two different repositories repo-1 and repo-2.
I had uploaded some 50 odd Maven dependencies to GitHub Packages registry of repo-1 and now we're migrating to repo-2. pom.xml and all the GitHub Actions workflows are being copied over as is. So I need to access the same set of dependencies in repo-2 for the Maven build workflows. However, repo-2 is unable to download the dependencies from repo-1 Packages registry.

Workflow snippet:

- name: build
  run: mvn clean package '-Dmaven.test.skip=true' '-Dmaven.wagon.http.pool=false' --file pom.xml -B -X
  env:
    GITHUB_TOKEN: ${{ github.token }}
    MAVEN_OPTS: -Xmx3072M -Xss128M -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=2048M -XX:+CMSClassUnloadingEnabled

Repository config snippet from pom.xml:

<repositories>
    <repository>
        <id>central</id>
        <url>https://repo1.maven.org/maven2</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>1_maven.apache.org</id>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
        <url>https://repo.maven.apache.org/maven2</url>
        <layout>default</layout>
    </repository>
    <repository>
        <id>github</id>
        <url>https://maven.pkg.github.com/Org/repo-1</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
        <releases>
            <enabled>true</enabled>
        </releases>
    </repository>
    <repository>
        <id>jasper</id>
        <url>https://jaspersoft.jfrog.io/jaspersoft/third-party-ce-artifacts/</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
</repositories>

I've admin access to both the repos and here're a few things that I tried:

1. Some access control settings from the official documentation, especially this - Connecting a repository to an organization-owned package on GitHub. Connect Repository button doesn't appear in my case.
2. Used default GitHub token as well as my PAT. (PAT has required access to packages and SSO authorized)
3. Used -X switch. Surprisingly debug logs don't show why exactly the dependencies couldn't be fetched.
4. 2nd and 3rd accessibility options on repo-1 as shown in this snap -

However, nothing worked so far.
