Start-Process Elevated Powershell & Send a Variable to Be Used When Running Elevated Script

When this scirpt is executed(non-elevated) this script asks password and maps onedrive and then it automatically launch powershell(elevated) and asks again password for bitlocker.

If single password is used for onedrive and bitlocker, how to make it to require password once? Or is it possible to pass variable(contains user input password) to new elevated powershell to be used in script to unlock bitlocker?

    $currentUser.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator)
}

if ((Test-Admin) -eq $false)  {
    if ($elevated) {
        'tried to elevate, did not work'
    } else {
