frogbot: could not determine the package manager / build tool used by this project for Dotnet Projects

We Followed similar pattern for Dotnet Project and Kinda getting below pasted error

19:09:20 [Info] Running Frogbot "scan-pull-request" command 
19:09:21 [Info] Auditing project: /home/runner/work/test/test
Error: 1 [Error] audit command in /home/runner/work/test/test failed:
could not determine the package manager / build tool used by this project.
Error: The process '/opt/hostedtoolcache/frogbot/[RELEASE]/x64/frogbot' failed with exit code 1

It would be good to have enough documentation for Dotnet. My Github action workflows looks like below:

name: "Frogbot Scan Pull Request"
on:
  pull_request_target:
    types: [opened, synchronize]
permissions:
  pull-requests: write
  contents: read
jobs:
  scan-pull-request:
    runs-on: ubuntu-latest
    # A pull request needs to be approved, before Frogbot scans it. Any GitHub user who is associated with the
    # "frogbot" GitHub environment can approve the pull request to be scanned.
    environment: frogbot
    steps:
      - uses: actions/checkout@v2
        with:
          ref: ${{ github.event.pull_request.head.sha }}

      # Install prerequisites
      - uses: actions/setup-dotnet@v2
        with:
          dotnet-version: "6.0.x"

      - uses: jfrog/frogbot@v2
        env:
          JF_URL: 
          JF_ACCESS_TOKEN: ${{ secrets.ARTIFACTORY_DEPLOYER }}
          JF_GIT_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          JF_INCLUDE_ALL_VULNERABILITIES: "TRUE"
          JF_REQUIREMENTS_FILE: "test/test.sln"
