Hi @Diya1,
If you have no Azure, it is impossible to send approval to external approvers, but if you have it, you could share and assignment to people in other organizations by creating Azure Active Directory (Azure AD) guest users—approvals are still in the original organization so that they can be managed by their tenant administrators. However, users from other tenants can be invited as guests and then assigned roles, giving them permission to participate in processes.
Or you could refer to @yashag2255 's workaround, using the "Send email with options" action to achieve it.
