    .PARAMETER ProjectId
        The project id for the Dynamics 365 for Finance & Operations project inside LCS
         
    .PARAMETER BearerToken
        The token you want to use when working against the LCS api
         
    .PARAMETER LcsApiUri
        URI / URL to the LCS API you want to use
         
        The value depends on where your LCS project is located. There are multiple valid URI's / URL's
         
        Valid options:
        "https://lcsapi.lcs.dynamics.com"
        "https://lcsapi.eu.lcs.dynamics.com"
        "https://lcsapi.fr.lcs.dynamics.com"
        "https://lcsapi.sa.lcs.dynamics.com"
        "https://lcsapi.uae.lcs.dynamics.com"
        "https://lcsapi.ch.lcs.dynamics.com"
        "https://lcsapi.no.lcs.dynamics.com"
        "https://lcsapi.lcs.dynamics.cn"
        "https://lcsapi.gov.lcs.microsoftdynamics.us"
         
    .PARAMETER RetryTimeout
        The retry timeout, before the cmdlet should quit retrying based on the 429 status code
         
        Needs to be provided in the timspan notation:
        "hh:mm:ss"
         
        hh is the number of hours, numerical notation only
        mm is the number of minutes

        Each section of the timeout has to valid, e.g.
        hh can maximum be 23
        mm can maximum be 59
        ss can maximum be 59
         
        Not setting this parameter will result in the cmdlet to try for ever to handle the 429 push back from the endpoint
         
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions
        This is less user friendly, but allows catching exceptions in calling scripts
         
    .EXAMPLE
        PS C:\> Get-LcsDatabaseBackupsV2 -ProjectId 123456789 -BearerToken "JldjfafLJdfjlfsalfd..." -LcsApiUri "https://lcsapi.lcs.dynamics.com"
         
        This will get all available database backups from the Asset Library inside LCS.
        The LCS project is identified by the ProjectId 123456789, which can be obtained in the LCS portal.
        The request will authenticate with the BearerToken "JldjfafLJdfjlfsalfd...".
