Hello @Krupa Gundraju (Larsen & Toubro Infotech Limit) ,
Welcome to the MS Q&A Forum.
If I understand your question correctly, you are looking for the UserMemberSettings to set the notifications parameters.
Below are the optional query parameters for Set-AzureADMSPrivilegedRoleSetting cmdlet for userMemberSettings. As we could see, It seems you can't configure notifications by using this specific cmdlet.
"userMemberSettings": [
{
"ruleIdentifier": "ExpirationRule",
"setting": "{\"permanentAssignment\":false,\"maximumGrantPeriodInMinutes\":480}"
},
{
"ruleIdentifier": "MfaRule",
"setting": "{\"mfaRequired\":false}"
},
{
"ruleIdentifier": "JustificationRule",
"setting": "{\"required\":true}"
},
{
"ruleIdentifier": "ApprovalRule",
}
]
Reference: List governanceRoleSettings
As a workaround, you could manage role settings through Microsoft Graph and set these parameters in the request body.
Hope above answers your questions and concerns.
Sincerely,
Olga Os
